Heat pumps operate in one of two modes: with reversing valve and unit operating in the cooling phase when the solenoid coil is de-energize or with valve and unit operating in the heating phase when the solenoid is de-energized.

A reversing valve a type of valve and is a component in a heat pump, that changes the direction of refrigerant flow.

By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa. Overview: Valve failures will generally be one of three failure modes: 1. Stuck somewhere between heat and cool positions. Coil failure is usually fixable. Hydro Royal Swimming Pool Heat Pump.

The unit cooled great for about minutes.

TROUBLESHOOTING HEAT PUMP SYSTEMS… REVERSING VALVES. Stuck valves could be the result of a pilot or main valve problem. The first step to diagnosing high-back and low-head symptoms is to determine if the evaporator coil is flooded with. I show the symptoms of a stuck reversing valve. This one is stuck partway and is bypassing from high side to low side.

This video is part of the heating and cooling series of training videos made. Discover How To Repair Anything! DIY supplies for your home or garden needs. Order From HVACPartsShop Today!

The first step towards diagnosing a leaking reversing valve is making sure that there are no other issues that could possibly mimic reversing valve or compressor problems. One such issue is a liquid bypass, which occurs when the evaporator coil becomes flooded with liquid refrigerant. You have been signed out due to in-activity the last minutes.

This solenoid-operated valve is a slide type design with a 4-way pilot valve and it operates under the full pressure of the heat pump system. Solenoid coils are not include sold separately. Available Wwiring harnesses are shipped separately. Wiring harnesses can be specified at various lengths, terminations, and identification. CARRIER EF17BZ2REVERSING VALVE WITH COIL REVIEWS.

Be the first one to give the review. I ohmed the valve and it read 6.

How much should the resistance be and how can i differentiate the problem, valve or coil ? The energized state is achieved by applying voltage to the coil , which is commonly used in Air conditioning. The heat pump can be designed by the manufacturer to produce cooling or heating with the reversing valve in the de-energized positition. The thermostat should send the volts to the reversing valve coil through the “O” wire on your thermostat.

If the reversing valve coil is getting volts and not shifting then you might need a new reversing valve. I hope you can find an easy inexpensive solution to the problem. It is used at room air conditioners, packaged and central air conditioners. Heating, Ventilation, and AC (HVAC) Equipment for Professional Contractors. Actual retail prices may vary by dealer.

Encapsulate continuous-duty, moisture-resistant magnetic coil is designed to operate the pilot valve controlling a reversing valve.

Class A rating and suitable for operation at over and under rated voltage. Instead of cooling a building, it will provide heat. Signs of failure may be intermittent. The reverse is accomplished by the use of electromagnetism. However, the new solenoid coil bodies are different and are NOT backward compatible or interchangeable.

As shown in Table below, there are new reversing valves using new solenoid coils. Finally, the four-way “ reversing valve ” was develope and is in use today. Reversing valves may become stuck due to sludge and debris. In a heat pump, the compressor may be the heart of the system, but the reversing valve is the nerve center.

Two types of reversing valves were develope a poppet-type and a slide-type. Have any of you guys ever had problems with reversing valves getting stuck in either cooling or heating on heat pumps? I have Whalen Heat Pumps which are heat active (meaning 24Volts at coil in heating mode) Which have been a pain in the A__! The thermostats are supplying the volts to coil , and I can hear the clicking sound at the coil. A way reversing valve is used to swap the functions of the evaporator and condenser in order to change from cooling to heating mode.

To avoid confusion it is common practice to call heat pump coils the indoor and outdoor coil.
