I have a weather king furnace and the furnace runs all the time.


first check your high limit switch find the white wire coming from your blower moter and unplug it hold down your door switch to see if your furnace will shut off if not replace it and your blower will run for ten to 20 min or until your heater has cooled down.

Goodman furnace GMP075-3 The thermostat was in the off position over night and sometime during the night, the induced blower and blower motor came on. The trouble light on board blinks 5 times. I checked...


Need your model # to check the codes but, this coming back on after turning the t-stat off is rare. You may have been in a lockout and the furnace re-started. Some furnaces try to start three times , then lock out. Time out, then re-start. The codes should be on your furnace blower door. Write back with this info and i could help.

I have an armstrong air ultra v, the ignitor switch or the blower won't come on, we ran the tank pretty low last year, so i'm not sure if we ran out, but we just filled our tank' any suggestions because...


First make sure that your thermostat is turned to heat and auto settings. Then turn up t-stat to where it should be calling for heat.If nothing happens then make sure you have power to heater, gas valve is turned on and blower compartment door is securely latched. If still nothing turn t-stat to fan on and the blower should come on and run until you shut it off. If it does this then you know that you have power to furnace and that the blower works.After you are sure that you have power then remove thermostat cover from base. If stat wires are connected to front of base then disconnect red and white wires and temporairly touch them together. This should send power to your furnace and start the ingnition cycle. If this works then replace thermostat. The sequence of events in the ignition cycle are t-stat calls for heat, induced draft motor comes on and runs for about 20 seconds,then ignitor comes on and lights pilot,then burner lights for 1-2 mins and then blower comes on. I would start at the t-stst and work my way through it. If I can be of any help please ask. Thank you

I have a ruud deluxe 80 plus furnace, the blower keeps running and it wont shut off. i have turned the thermostat off and its still running, what could be wrong?


Hi,
That could be a couple of things....
Open up the bottom cover and take the wire off of the "G" terminal that goes to the t-stat...then replace the cover and see if the blower still runs...
If it runs then the problem is intenal to the furnace, probably the integrated control board or a high limit is tripped...
If that stops the blower from running then you have a bad relay in the t-stat ora shorted wire going to the t-stat.

If the unit fires but the main blower fan doesn't come on the the unit is shutting off on a temp high limit switch and it sounds like the problem is the main blower fan motor or control

Blower isn't coming on and the outside unit isn't shutting off?


either bad blower motor, or capacitor for blower motor is bad or thermostat not telling blower to come on try to take the wires off t-stat be carefull which one you touch it is low voltage but you dont want to blow a transformer. use as wire and touch the g and r terminals and see if it comes on if it does it is your t-stat if not issue is at furnace or airhandler

GMPN 100-4 furnace. Blower motor runs when not calling for heat.


The board is bad. The unit thinks a flame is present, so it tells the blower to come on. Replace the board.

Blower fan wont shut off


Try cycling the switch at the furnace to reset the blower board. If this doesn't work remove the green wire from the blower board(computer board) to eliminate a shorted t-stat or shorted wire between the furance and t-stat. If blower remains on, then blower board is shorted. I've seen all these problems.

Fan will come on for heat(auto), but not for AC or set to ON


You have a blower relay in the furnace that's probably bad. In the heat mode the blower is on a temperature relay, in cooling mode the blower has to come on immediately so there is another relay for cooling. The green wire on the thermostat feeds that relay, so if you go to the furnace and shut the power off and find the green wire from the thermostat that feeds that relay and replace it, being careful to mark all the wires before removing them, also the relay terminals have numbers for identification.
