My fan doesnt always turn on when my heat pump does and it

This answer was rated:

My fan doesn't always turn on when my heat pump does and it will run and run until the heat pump makes a screaming noise and my temp will fall finally enough and then finally the aux heat kicks on with the fan. Sometimes my fan comes on with the heat pump and sometimes not. You can turn the switch to on while its in heat mode sometimes it will turn on and sometimes not
I need make and model of Unit please. Rus

Will you be on tomo? I am at work now. All I know is its a goodman heat pump.
That answers my question bad fan relay. Goes out all the time in Goodman units. I carry two relays for Goodman units at all times. This looks like a sequencer and is located in front of unit. The noise you are hearing is the compressor going out on internal pressure relief. Rus

So the relay will work sometimes and sometimes it won't is that what you are telling me? Why does the fan work with aux heat?

In aux. heat it puts power to fan motor thru heat sequencer. Different relay. Rus

Ok do you have a schematic sheet of location and what it should look like?
There is one on the inside of your unit. Located on the blower housing. When you open unit the fan relay is the front relay. It does not look like a relay. It looks like a sequencer. It has to be single pole double throw sequencer. Rus

So the one on ebay is good to go? This is driving me crazy. Right now its working like its supposed to. Is that normal?
These switches will work and not work. If the thermostat has heat strips kicked in the fan is running off electric heat sequencer. Rus Ebay is OK.
