Fan runs but a/c is not working - Goodman Heating & Cooling

Cooling fan is controlled by a relay and a temp sensor. You need to check that each piece is working.
Run power to the fan. fan run? fan ok.
Bridge the relay. Fan run? run power to the relay coil. Fan run? relay good.
find temp sensor. replace.

What fan is not running? The case cooling fan or the CPU cooling fan? Did you try to boot into Safe Mode, and did the computer/screen start working then?

The door switch, some fridges run the fan on door closed only.

when microwave is running the fan sounds like it is grinding

These will help.

Thanks.

This can be due to a bad relay or coolant sensor that turns on the fan or a bad fan, a good test to do to see if the relay and the fan work is to start the engine and then turn on the ac, if the ac doesnt work then unplug the coolant temp sensor this will turn on the check engine light but it will reset when you restart engine, if the fan turns on then fan and relay are good and its the sensor, if the fan doesnt run then it may be the relay or fan, a quick test of the fan is to dissconnect plug to fan and run a power and ground wire to fan and if it runs then you have a bad relay,hope this helps,

mcdevito75 here, You say fan worked in the past, That tells me the fan has not run in over 1 month if so, try this. First, the fan motor is a sealed unit, without running the fan in over 1 month it may be a little stiuck, put the fan lights on, and pull the fan chain just once and turn the fan blades themselves just a little to get thm started. also verify fan switch itself is good, Chain switch should have the familiar click click to it. If not the fan swich could be bad.

One fan should run when engine is running. Other fan should run when AC is on.
