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.

the pressure switch is closed before the draft motor closes it.the board is telling you that this is not right.pull the wire(either) off of the pressure switch to see if furnace tries to light.if it does,you should replace the pressure switch.

The blower relay on the circuit board is likely stuck closed. It looks like a black square on the board.

it does sound like a limit switch to me as well. Make sure the fan switch on your thermostat is set to "auto" and not "on"

I have a coleman furnace model 4066A656


Make sure your air filter is clean. Is the thermostat satisfied? or is the room temp. still below the thermostat setting? When ever you have to turn the power off and then back on to a furnace that usually indicates that the furnaces ignition control locked out. The first thing that I would try is cleaning the flame rod.

Trouble shoot Dayton gas furnace model GG9S100C16MP11A fan is left on constant but in cold weather 10 or colder fan will go off and furnace will go thru a restart mode and run fine for awhile then will do...


Do not run contentiously during heat mode. the fan runs at a slower speed with heat and heat fires first then the fan cycles on during heat cycle then when heat satisfies the thermostat the heat will cycle off and fan will run for a couple more minutes and then cycle off. So set stat on fan cycle to auto.

I installed a run capacitor for my blower motor on my RUUD ac model UGPH10EBRJR. now it runs all the time. I even disconnected my thermostat and it kept running. is it my thermostat? or something else


An open limit switch may make the fan run all the time. Try disconnecting the Green wire @ the furnace...if that does the trick, then either the thermostat fan relay is stuck, or there is a short between the Red & Green wires somewhere in the thermostat wire.

Have an older Coleman mobile home furnace (Mdl 8665D766). Both blower fan and booster motor work fine; however, during heating, booster motor will keep constantly running after system cycles through


The booster motor? Do you mean the inducer motor that helps push the exhaust? If the inducer motor won't shut off when the thermostat is satisfied and everything else does shut off, it sounds like the contacts on the relay that powers the inducer are at fault

Carrier troubleshooting furnace


If the thermostat isn't selected for "FAN" then the relay is stuck. In heat mode the thermostat opens the gas valve and starts the igniter and the induction motor. If the induction fan isn't running, the flame will stop.

WEATHER KING GAS FURNACE . BLOWER MOTOR COMES ON INSTANTLY ON CALL FOR HEAT AND WONT SPARK IGNITE.


You have a high temp safety open. The control board sends a signal through all safeties first. And if there is a safety open, the board believes the unit is overheating, so it engages the blower to cool it down. The safeties are normally on the blower assembly, near the burners, and near the heat exchanger. Hope this helps!

I would first eliminate one furnace from the equation, the exterior wood furnace... turn its tstat down. Will the gas furnace then operate normally? Can you run the blower manually, as in summer mode? Make sure your filters are clean also... that can sometimes overload the blower.

I have a weather king model 90RJ - first time I've had hot air heat..When I turn on the heat, the blower turns on right away ( blowing cold air) - I understand that the ducts have to cleared of the cold...


When the furnace first comes on there is a induced draft motor that should come on first but that forces air up the exhaust or flue,not into supply air on ductwork. It is not unusual for cold air to be blown out when burner first turns blower motor on. This should last for a short period of time, no more than a min. or two. You can watch furnace cycle by removing top front cover, I should back up here and ask is this a gas or electric unit. If it is gas you should be able to watch burner flames for a short time before blower comes on. I really need more information so I can try to ascertain what is going on. Wish I could be more help. Thank you.

Outside heating unit runs all the time


Usually when the furnace blower motor runs all the time
The limit switch or rollout switch is usually open or bad.
The furnace board is seeing that one of those switches is open, so it brings the blower on to try to get the heat out of the combustion chamber area, so the switch will close. But if the switch is bad and won’t close, the furnace board will keep the blower running continuously.
