Tip

On a heat pump the difference between haet and cool is the reversing valve


On a heat pump the difference from heat to cool is the reversing valve.
In cooling or heating the Y1 terminal will always be energized, this is the contactor.
Depending on brand the reversing valve will either be energized in Heat or Cool. At the outdoor unit check to see if the reversing valve is getting 24 volts in cool, if not check to see if it is getting 24 volts in heating. The easiest way to check if the reversing valve is shifting, is to feel the big copper tube, (it is not the suction line on a heat pump) this is a refrigerant vapor line. It will be cold in cooling and hot in heating.
Check your thermostat installation instructions and heat pump installation instructions to determine the proper terminal designations for your heat pump and thermostat. There are some brands out there that use the B terminal as common to the 24 volt circuit, so you have to check the wiring and make sure this is not common.
If it is energized in Cool then the Y1 and O terminal will be energized. You will have 24 volts from common usually the C terminal to Y1 and O.
If it’s energized in Heat then the Y1 and B terminal should be energized. You will have 24 volts from common usually the C terminal to Y1 and B.
If you get heat when you’re calling for cooling or vice versa then switch the wire between the B and O terminals.

Can somebody help,why is my Central AC blows


Most heat pumps have an auxillary heat. Many are electric auxillary heat with a heat strip in the air handler. A common malfunction is for the electric auxillary heat to operate when the heat pump is set on cool. To confirm this, locate the conductor that runs from the heat sequencer to the connection on the heat strip. You will see this on the top section of the air handler. Use the clamp on part of the amp meter over that wire. If the thermostat is set on cool and the heat strip is drawing amps, it means the heat is coming on while the heat pump is set on cool. There is usually one or two causes for this, either the sequencer is bad or there is low voltage wires usually behind the thermostat or in the air handler closet that are touching that shouldn't be touching.

If this is not the case, if its not a problem of where the heat is coming on with the air conditioner, it could be a case of the reversing valve malfunctioning. The way a heat pump works is it reverses the flow of the refridgerant. For instance, many heat pumps the reversing valve is activated in cool. That would mean that there is a low voltage circuit that activates the reversing valve when the heat pump is in cool. I'm not sure what model/brand your heat pump is, Goodman and Janitrol for instance, the heat pump reversing valve is activated in cool. In any case, if the reversing valve is not operating properly, when the air conditioning is set to cool it will actually be heating. Or you could set it to heat and it may actually be cooling instead of heating. Please check these two items first and if you have any further questions, please let me know. Especially if you know of any additional problems like the evaporater is icing up or if the air handler fan is not operating when it should.

Hi- Can not tell if my unites are straight cool / heat or a heat pump.


if you look inside the condenser unit outside,see if you see the big reversing valve,if not it is a straight cool,heat, the heat strip ins in the air handler so you would have to take the side panel off and look for the heat stripe,my the way heat pumps also have a aux.heat stripe just in case it does not get cold enough outside,hope this helps you-mike
