Troubleshooting a bad reversing valve coil. what should the voltage read on the wires. the coil is 208/240 - Answered by a verified HVAC Technician Chat 1:1 with a hvac technician Licensed Experts are available 24/7. 100% satisfaction guarantee Get all the answers you need. Ask Glenn Your Own Question. Glenn, maintenance technician The high voltage side takes 110 to 240 volts AC and transforms the voltage to 24 to 28 volts AC. If the contactor is not getting the 24 volts to the contactor coil then it could be a time delay relay (if the unit is equipped), thermostat problem, transformer, safety control (low on refrigerate) or wiring problem There are two valves in the reversing valve assembly. The solenoid is energized by 24 volts when the thermostat mode is set to heating operation. The nose slide valve is positioned by the pilot valve. Use the ohmmeter to check the 24-volt pilot solenoid. Do not energize the solenoid without the reversing valve pilot stem in place in the coil REVERSING VALVE PROBLEMS . Problems experienced with reversing valves fall into four general categories: 1. Valve will not shift from cooling to heating. 2. Valve will not shift from heating to cooling. 3. Valve starts to shift but does not complete reversal action. 4. Valve suffers apparent leak when shifting
This is a Goodman PHJ030-1A package heat pump. First: question is will low freon stop the reversing valve from switching? (Yes or No) Second: I check the reversing valve coil and found 24 volt going to it, it had 17.6 ohms Low control voltage can cause a reversing valve not to shift. This is a very common issue on commercial units where there is 208v and the transformer is not configured properly. If control voltage is present, is the solenoid creating a magnetic field? One of the easiest ways to test this is by removing the solenoid from the reversing valve body. When the solenoid is not working correctly, it will not energize the valve, making it get stuck or sometimes overlook the energizing process and eventually turn off mid-operation. To check if it is an electrical problem, you will have to make sure the reversing valve is energized by merely using a voltmeter to review the voltage of the solenoid
The wire connected to B on the thermostat is what sends voltage to the reversing valve when you select heat.In the cool mode, it should not be sending 24 volts to the solenoid. Ask Your Own HVAC Question Customerreply replied 8 years ago OK one last question for the night 1. Valves Do Not Open. Solenoid valves may not open because of power failure, uneven pressure, wrong voltage, dirt under the diaphragm, corrosion, missing components, or a burnt coil. However, since there are so many causes, you must try to narrow down the problem in order to fix it If the reversing valve gets very hot very fast, the problem is the reversing valve. If you still cannot determine which is the problem, it most likely is the compressor, because the location where you touch the compressor is removed from the source of the hot gas If the contactor is open and not getting 24 volts to make the contacts close then you have a low voltage problem like a thermostat, thermostat wiring problem. If the contactor is energized and closed with 24 volts going to the contactor coil then I would suggest that you check the contactor to make sure the contactor is good by testing for.
The reversing valve exists to change the direction of the refrigerant. Twenty-four volts from the defrost board energizes the solenoid on it. On 90% of the systems out there, the reversing valve defaults to heating mode. This way, if the valve is not working or doesn't have 24 volts flowing to it, at least the heat still works Either the solenoid was loosing power after several minutes, or it was not able to keep the reversing valve moved to cooling mode. There is a relay on the control board that uses a 12 volt DC signal from the wall thermostat to turn on the 120 volt AC current to the solenoid. When you turn your wall thermostat to Cool, it activates the relay. Not only is my solenoid coil physically different (also causing it to function differently by design), but the wattage I received was for 5/6watt applications. I really wish this detail was a necessary part of Amazon's description for these types of items.

Measure the voltage at the relay coil when the relay is trying to close. If it is much less than 24 volts (the nominal on your transformer) you have a voltage drop in the circuit controlling the relay. A bad switch, bad connection, too small wire or too long, or an inadequate transformer are possibilities I tried to look at the voltage between O and R. So I used a digitail volt meter in DC mode to see if the thermostat is now sending 24V to the reversing valve. R is the Positive and O is the negative. Although with a digital volt meter it would just read a - if I got it backwards, but it would still read the voltage
In this video we take a look at how a reversing valve works in a heat pump, we explain the basic operation of a split system air-source heat pump as well as. This video will help you diagnose and troubleshoot low voltage issues you may be having with your thermostat (red wire) using your multimeter... as well as f.. leaking slider valve A reversing valve on a heat pump is an electrically initiated, and pressure operated valve. In essence it is two valves in one; the main valve with the slider body, and a smaller pilot valve that directs pressure to the main valve. Depending on the system, the valve can be energized by either the O or B terminal fro Make sure you are getting power to the valve solenoid coil in the AC mode by checking for 24 volts.. If not then it might be another control circuit issue like thermostat or control board in the heat pump that is a lot less expensive to fix than bypassing the valve Diagnosing Stuck Reversing Valves. The first step of diagnosing a stuck reversing valve involves checking the reversing valve solenoid or pilot valve, which should be energized when the heat pump is in heating mode or cooling mode, depending on the manufacturer. Use a multimeter to check for 24-volt power at the solenoid's wiring connections.
1. The Heat Pump terminals accept the 24 VAC signal from the reversing valve holding coil. Make a parallel connection Symptomfrom the reversing valve to the HP terminals. Note: Do not apply a voltage higher than 30 VAC to the HP terminals. 2. If the Heat Pump is in the Heating mode and the reversing valve is energized, then the Heat Pum I see techs in the field get the most frustrated when they have a low-voltage short they can't seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and some root misunderstanding about what they are looking for. First, let's work to get a handle on what sort of issues exist and what they're called
reversing valves installed in heat pumps operated on 24 volts DC power. Therefore, if a DC solenoid valve fails on any unit built and shipped prior to March 1, 2005, the replacement solenoid coil will likely be 24 volts AC power. The new 24-volt AC solenoid coil will not work with the old Mark IV controller (Figure 1) and likewise, a new Mark. Replace reversing valve. Unit will not run: a. Power off or loose electrical connection: a. Check for unit voltage at contactor in unit. b. Thermostat out of calibration set too high: b. Reset. c. Defective contactor: c. Check for 24 volts at contactor coil replace if contacts are open. d. Blown fuses or tripped breaker: d. Replace fuse or. I have a Goodman package heat pump model PHJ030-1A. I found a leak in the condenser coil, in the U shape joint. I made some checks, reversing valve coil: the resistance was 17. Something ohms, found 24 volts going to the coil, but didn't check for amps. O.K. Would low freon stop the reversing valve from switching to heat mode? O.K. Let say that the leak was fix, what would stop the valve. Operation. The reversing valve has two states, relaxed (unactivated) versus energized. The energized state is typically achieved by applying 24 volts AC, which is commonly used in HVAC equipment. The heat pump can be designed by the manufacturer to produce either cooling or heating with the reversing valve in the relaxed state
Broken reversing valve: As the name suggests, the reversing valve allows the heat pump to work as both a heater and an air conditioner by reversing the direction of the refrigerant. If the heat pump turns on when you want cool air, but not for heat, this is likely the cause. It will also need to be replaced by a technician The two possibilities in this case are a failed thermostat or a problem with the thermostat wiring that is preventing a circuit to the 'O' connection on the low voltage terminal board. Without 24 volts applied to this terminal, the reversing valve solenoid isn't energized, preventing the system from shifting to the cooling mode

Accordingly, how do you energize a reversing valve? The reversing valve has two states, relaxed (unactivated) versus energized.The energized state is typically achieved by applying 240 volts AC, which is commonly used in HVAC equipment. The heat pump can be designed by the manufacturer to produce either cooling or heating with the reversing valve in the relaxed state Thermostat Wiring Diagrams for Heat Pumps - Heat Pump Thermostat Wire Diagrams. Heat pumps are different than air conditioners because a heat pump uses the process of refrigeration to heat and cool.While an air conditioner uses the process of refrigeration to only cool, the central air conditioner will usually be paired with a gas furnace, an electric furnace, or some other method of heating The air handler sends a 24-volt power source to the thermostat through the wire with red insulation. Step 4 The O and B terminals on a Honeywell digital thermostat send power to a heat pump's reversing valve. The O terminal operates the reversing valve during the cooling cycle and the B terminal operates it during the heating cycle In this case, the source is the transformer, the load is the thermostat, and the path is the R terminal and the C terminal which provides the path back to the 24-volt transformer. O Terminal: The O Terminal is the control for the reversing valve in most brands of heat pumps Check the line voltage over a 24-hour period. If ambient temperature is too high, the coil's ability to dissipate heat by radiation is reduced. An overheated coil's resistance increases, current flow and force are reduced, and the solenoid will not close, resulting in coil burnout again. Check the cycling rate
The most common problem with the reversing valve is the solenoid coil failure and when the valve is stuck in the heat or cool mode, or somewhere in between. To solve the problem with the solenoid, check the voltage to see is the coil short out or open. This eliminates problems with the wiring. Solenoid can also be easily replaced It is typically used to bring power to the reversing valve and is used for a heat pump with a reversing valve where the normal (un-powered) position is for heating. If you're using the O terminal you will NOT use connects R-G then the 24 volts from the transformer flows to the contactor coil via the 24 volts AC supplied to C and G. 1. To verify this, check for 24 volts between DFT and C on board. 2. If the temperature at the thermostat is less than 28°F and the thermostat is open, replace the thermostat. 6. When the defrost thermostat has closed, short the test pins on the board until the reversing valve shifts, indicating defrost. Field Testin

Reliatel units need the reversing valve energized for cooling. If the thermostat doesn't supply 24 vac to the G terminal the Reliatel board will still turn on the indoor fan when needed. What the terminals do: Y1 - Stage 1 cooling mode or turns on both compressors (if a dual circuit) in heat mode. W1/O - Energizes the reversing valve Most reversing valves stick due to a bad solenoid coil that lacks enough voltage to move the reversing valve. In some cases, the actual valve could be physically stuck, preventing the solenoid coil from moving the valve. Tapping on the valve may get it unstuck temporarily, but you'll eventually have to have an experienced HVAC technician deal. This ends the 24-volt signal to the compressor contactor and the outdoor unit stops. 14. This ends the 24-volt signal to the indoor blower relay and it stops. 15. The system is now off. The reversing valve pilot solenoid stays energized as long as the thermostat is set for heating Four-way pilot valves are being used more and more, as evidenced by Alco using 4-way pilot valves on their new series of reversing valves. Older style 401 Alco valves used 3-way pilot valves. Four-way pilot valves are more expensive than 3-way, but they last longer and have more spacious cavities in them to allow system debris to pass rather.

Low Voltage (24 volts) Not Present Between Blue and Brown Wires Reversing Valve Stuck In Cool Mode Defrost Relay Contacts Bad (dropping 24 volts to reversing valve coil The reversing valve works in a sliding mechanism; this allows the valve to change the directional flow of the refrigerant in the system, which is how your heat pump changes between modes. A reversing valve can become stuck in a certain position, be it a mode or in-between modes, for a few reasons. Sometimes a stuck reversing valve can be.
As the valve slides, the refrigerant also helps the valve to change states between relaxed and excited, or vice versa. Once the valve has slid into the correct position, the mode has changed.
