Sounds like your control board is shorted.Without actually checking the unit this is a guess.

My blower motor wont turn off in my furnance?


check the fan setting on your thermostat. On means always on, auto/int means only comes on during heating/cooling. if the thermostat is set to auto / int and the fan keeps running? you may have a bad fan relay switch. It may be integral on the primary control board of your unit.

The indoor fan or the outdoor fan? If it is the indoor fan the thermostat may be wired incorrectly or shorted. If the red wire and green wire in your thermostat maintain contact, the indoor fan will run all the time.

Have a Janitrol central air system and the unit outside comes on but the fan in attic does not always come on. If I go to the thermostat and manually turn it from auto to on it comes on. Any ideas about...


If the blower is working with the thermostat in the ON position that tells you that the fan motor works. In the AUTO setting... the system in controlled by the contacts in the thermostat. 1. The thermostat contacts might not be closing. 2. A contactor( or relay ) in the air handler unit(inside unit) might not be closing to send the signal to the fan motor. It sounds like a thermostat or relay problem to me. You can email me at Starztruck4u@aol.com if you have more questions.

Check the unit for a high temperature limit switch, usually a round bimetal disc or a square plate that
would insert into the unit. If the switch is bad, it opens up and the fan will run no matter what. Complete the circuit with jumper wire, if fan shuts off
replace switch

I just changed the control board in my york furnace the old one shorted out upon putting the new one in it gives me the trouble code of the led blinking 9 times and the big blower runs continuously please...


On the back of the bottom door, is a led code which will tell you what could be wrong. I would turn power off, disconnect the thermostat wires, but unit back
together turn power on, blower should not run.

Next make sure fan switch at thermostat is not in the on position. Turn power off and put a jumper between
r and w. Turn power on the blower may come on and
then shut off, heat should come on and then blower
again. If this is true, then you have a problem with
the thermostat or thermostat wires, make sure these
wires are not touching

Indoor fan motor continue to run even if the thermostat is in auto position with the cool and heat switch in the off position. The furnance don't have a fan on and off switch in the furnance like most....


Try this, disconnect the fanwire (green) on the furnace, if it shuts off then the hot wire from the thermostat is touching the green wire or bad thermostat. Thank-you-very-much!
