Video of a confirmed diagnosis of a 3-way reversing valve not cooling but heating ok. I ohmed the valve and it read 6.

How much should the resistance be and how can i differentiate the problem, valve or coil? Each part is a genuine OEM part. Services: Grainger Lighting Solutions. High Quality, Large Selection, Ship Today! 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. What you are most likely experiencing is the time delay of the pressure of the refrigerant in the pilot tubes not moving the reversing valve rather then the solenoid not energizing or de-energizing. This product does not comply with the Safe Drinking Water Act, which requires that products used in any system providing water for human consumption (drinking or cooking) to meet low-lead standards.

A heat pump reversing valve is an electro-mechanical 4-way valve that reverses the refrigerant (Freon) flow direction, using an electrical magnet. It works very similar to your washer’s water valve or solenoid valve (pictured below). In Figures and the valve is piped to fail safe on heating. In order to fail safe on cooling, the indoor coil would be connected to reversing valve port and the outdoor coil connected to reversing valve port 2. It reverses the flow of refrigerant in the system to make the condenser into an evaporator and the evaporator into a condenser. The reversing valve is the most complicated valve we use in the HVAC industry.

HOW A REVERSING VALVE WORKS. 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. They are in fact, an assembly of two valves: the main valve which actually directs the refrigerant flow in the system, and a pilot valve which controls the main valve.

It may become stuck in a specific mode or in between modes. Reversing valve repairs should only be handled by trained professionals. Solenoid coils can be removed within the length of the valve body and can be shipped attached to the valve in a choice of positions. Available Wwiring harnesses are shipped separately.

Wiring harnesses can be specified at various lengths, terminations, and identification. I was quoted $5for a 4-hour job, but the part - Answered by a verified HVAC Technician We use cookies to give you the best possible experience on our website. The unit cooled great for about minutes.

As the blower motor fan and the compressor contactor are energized so is the reversing valve.

Troubleshooting a reversing valve can be tricky. Overview: Valve failures will generally be one of three failure modes: 1. Stuck somewhere between heat and cool positions. Check out these common troubles and possible solutions. Coil failure is usually fixable. Thanks for looking and good luck!

ODF 6ton 24v Reversing 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. Refine your search for reversing valve solenoid.

Compromised wiring inside heating and cooling equipment can degrade performance and create a safety hazard. RA Series Refrigerant Solenoid Valves The 240RA is a 2-way, normally closed diaphragm valve. RA valves are used for liqui suction, and hot gas service. Commonly Reported HVAC Problems.

You Have Problems, We Have. This is usually caused by the reversing valve solenoid. Yes, this sounds like the reversing valve is not shifting. So if you have your thermostat set on “Cool” the reversing valve coil should be energized. Heat Pump Noise – Ductwork Installation – Introduction.

Then, these valves were combined with two valves, which became solenoid operated. Finally, the four-way “ reversing valve ” was develope and is in use today. In a heat pump, the compressor may be the heart of the system, but the reversing valve is the nerve center.

A solenoid valve is a device used to control the flow of liquid or gas in a system. Trane Reversing Valve Estimates. Quantity in stock for same business day shipping if ordered before 4PM CDT. A buzzing reversing valve is a common occurrence found on all brands.

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. 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.

If you suspect the valve is stuck, take a soft object like the plastic handle of your screwdriver and tap on either side of the valve body.
