depends on who makes it. some energize in heating and some in cooling.
Heat pumps have a reversing valve in the outside unit. You are hearing a balance of refrigerant pressures when the reversing is energized or de-energized.
If this is a reversing valve on a heatpump all you need do is to find out if you are getting voltage to the solenoid on the reversing valve. The solenoid is energized in either the heating or cooling mode, depending on the unit and normally receives its voltage from the orange wire from the thermostat. If you have no voltage to the solenoid in the cooling mode, switch it over to heat. If you still have no voltage, the solenoid or the control board is bad and needs to be replaced. If you have voltage, the valve should make a swooshing noise when the unit is switched from heat to cool/cool to heat. No swoosh, valve is bad. *First, if there is no voltage to the solenoid, then the problem does not necessarily lie in the solenoid, but from the source of its power: a relay, a control board, etc... *Second, the statement, "No swoosh, valve is bad" is common terminology used by people who don't completely understand how heat pumps and reversing valves operate. The "swoosh" is the refrigerant rushing sound heard when the slider inside the valve shifts positions. The slider is operated by discharge pressure from the unit's compressor. If the unit is low of refrigerant it might not have enough discharge pressure to make the slider shift, therefore no "swoosh" sound. A lot of reversing valves and compressors have been needlessly replaced by individuals who don't know what they are doing.
yes particle get energized by heat.
Hi, Good question and the answer is ( YES! ) as long <<<< as you are not taking up any fancy ideas of using it as a heat pump. Wire it in and set the reversing valve to stay on cool cycle and never reverse to heat and viola. Some units use energized reversing valve during cool and some de-energized. Its easy to find out. Just try it. Hope this helps: Jimiwane
My guess is you probably have a Heat Pump Condenser. If you are running in air conditioning you need to make sure that the reversing valve is energized.
there are 3 main reasons that your a/c is blowing warm during a call for cooling they are 1.the electric resistance heater is on 2. the reversing valve is energized in a Heat Pump, or you are low on refrigerant
the reversing valve is what actually changes the refrigeration cycle from heat to cool. the reversing valve receives its signal from the thermostat.
Solenoid is getting hot from heat transfer. Wire in a remote solenoid.
The reversing valve switches the flow of refrigerant from cool to heat inside and outside the home.
between the comp and the reversing valve
sounds like t stat is programmed wrong, reversing valve coil is bad or reversing valve is stuck.
Usually a minimum of 5: R (24 volt "hot")G (fan signal)W (heating signal)Y (cooling signal)O (reversing valve: usually energized for cooling)Many also require a 6th:W2 (2nd stage of heat--backup heat)Some thermostats also requireC (24v "common")More sophisticated systems may also requireY2 (2nd stage cooling)The HVAC Veteran
