the fuses are NOT just one fuse
and all mine are 240ac and also 120vac
even the thermostats have 24vac transformer that is 120v 20amp breaker.
mine has fuses for the compressor in the 200amp load center
and not any inside out door, compressor,/condenser.

there is no fuse, all are on breakers this is no 1950 year AC
why not post whats wrong.
screens on thermostats blank its backup battery dead.
check all breakers
check AC contactor for dead in compressor pad boxl
check AC capacitors
check both blower capacitors.
check for door interlock switches tripped

tell what is dead, AC or heat.
no clues at all, just false hunts for fuses no longer used on AC or heaters. they use breakers for 60 years.+
i guess is a heat pump and guess both modes dead.
all in one not split

get manuals from them
ask

check refrigerant charge. A low charge with cause what you are experiencing.

No reset button. As for low/high pressure switches they reset on their own when the problem is corrected. Usually low refrigerant.

Heat mode

Buy a heat kit from a Goodman dealer. Check that your existing wire will carry the amp load.

Check the filter & indoor coil...could be plugged up.

Check for plugged drain and/or broken plumbing parts.

is the gas turned on to the frunace? Is the switch on gas valve turned to on?

Check for stuck heat sequencer.
