Remove 1 of the 24volt wires from the transformer do you still have the problem? If you do reinstall the wire back to its terminal where taken loose then do the other wire. and see. If it shuts off with the red wire removed from the transformer 24 volt side the problem is a shorted wire from the furnace to the thermostat.

My gas pack won't light


First, the thermostat white wire is the wire that initiates the furnace to start. When you select heat on your thermostat the tech should get a 24-28 volts between the white wire and common on the thermostat wire in the furnace. If you do not get the required voltage, there is a break in the wire from the furnace to the thermostat that needs to be tracked down and eliminated.

FURNACE WON'T TURN ON: I have a 1999 Fleetwood, Prowler RV. The furnace won't turn on.


Check the exhaust port of the furnace. Wasps like to build nests in there and it will not allow the furnace to ignite if blocked. You have a gas detector and it is turned on I assume? I forgot this many times.

Fan is continuously running, even when turned off at the thermostat. vents blowing hot air.


Hello my name is Heath it will be my pleasure to assist you. The first thing to check is make sure the thermostat fan switch is set to auto instead of on. The next thing would be the High limit in the furnace or the rollout. If there is a sight glass on the bottom door of the furnace check to see if there is a flash code in the furnace then check it to the plate inside that has the flash code diagnosis chart.

Do i need to turn a switch on or off on my goodman unit or the furnace? how do i prep for the summer with out calling a tech?


There are no switches other than the breaker and outdoor disconnect that need to be on. Change your filter in the furnace. I would take a hose to the outdoor coil on the condenser to clean out any dirt and leaves on the coils. Do not spray on high pressure. Just get a good light pressure and spreay from top to botton perpindicular to the fins and up at a 45 degree angle. Other than that, set the thermostat to cool and you should be good to go.

Goodman Air Handler motor will not turn off.


Look at your Thermostat wiring.
If there is a green wire going to the "G" terminal, disconnect it.

If it stops running, you have a bad T-stat.

If it keeps running, you either have a stuck fan relay or a low voltage control wiring malfunction.
Those are usually related to one of the safety switches having problems.

If green is not going to G, let me know, and we will determine which one is indeed the fan wire and go from there.

Remember, when you rate the solution, it closes further dialog, so only rate when you are satisfied with the discusion.

Furnace won't stay on


Check your thermostat first. take of face of therm, disconnect wires, tie in red and white together, ,if your furnace runs ok, then your therm is bad. Thats the easiest way to test.

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.

Turn breaker on to furnace and the exhuast fon comes and ac will not come on


There should be two separate breakers for the cooling system. The furnace breaker you turned on. Now there should be a double breaker in the power panel labeled A/C or Air Conditioner. In addition there should be a disconnect at or near the outside unit. Make sure it is in the on position also. Set the thermostat to cool and the outside unit should start and run.
