I have the same problem with my Goodman compressor. I removed the relay so the wires that control the relay on the compressor are open circuit. They are, and the fuse no longer blows. There must be something wrong with the relay. The resistance on the 24 volt coil seems a little low, but it is not a dead short. I thought the wires might be shorted, but removing the relay would not have fixed the blowing fuse if that was the problem.

3 amp fuse blows when ac is switched on. Heater works fine.


There is a short in the low voltage wires somewhere for sure. The most common place is the low voltage on the outside unit, sometimes animals chew through them or they get cut with a weed eater. Just my experience. You basically have to trace it back all the way to the thermostat and heater. The only other thing is the contactor

I have a Carrier Weathermaker SX HVAC unit with a Honeywell thermostat. Even if the thermostat is turned "off", my fan keeps blowing!


Hello, usually this is a sign of a bad blower relay on the intergrated control board. The only option is to replace the control board.

My Carrier Weathermaker 8000 a few days ago the air began to blow non stop and the burners are not igniting. I am getting Code 33. I did all the resets, unplug control board, switch to air condition...


You need to look at the wiring diagram pasted on the door panel to get a starting point where to look. I suspect a bad pressure switch, jump it out and see if it starts.

My A/C (Carrier weathermaker 8000 hybrid) is not cooling properly


set the t-stat low and let it run for 5 minutes , stick a thermometer in the return air closest to the unit as possible until you get a good reading , then stick the thermometer in the cold air supply again closest to the indoor unit as possible let sit until it stops going down in temp.
this is called your temp difference and it should be atleast a 14deg. F difference from in to out. if its lower you have a refrigerant problem, Let me know how it goes.

Goodman Furnace/AC unit not working 3a fuse blows even after replacement. once thermostat is turned on and clicks to start ac unit the fuse blows


3 amp is standard.the fuse is blowing to protect the transformer.It is telling you that there is a short in the low voltage wiring.Goodman also had an issue with the coil shorting on the contactor.To prevent damage.....i'd call a pro.It should be a fairly simple repair.
