Bad connection. Shut off the power and re-crimp the connector or replace it. Take a picture of the connector and go to the hardware store and ask a sales associate for the connector.

SOURCE: Coleman Rooftop AC fan stops after 7 or 8 minutes of running. Will turn on again after about 10 minutes on its own.

Remove green (fan run) wire from thermostat, and connect to red wire (power) and see if fan runs, and if it will stay running. That will by-pass thermostat to see if it is problem. If it continues to run, thermostat is problem. If that doesn't cure it, I'd remove cover up top and with power off at circuit breaker, blow compressed air in to motor air holes to make sure it's getting proper air for cooling, as well look for small plastic plug on housing where oil can be added ( few drops) to lubricate motor. Leave cover off and try fan to see if that may help. If at all possible, a clamp on amp meter will confirm if motor or relay is at fault if none of these suggestions help. If amp draw at motor too much, motor may be seizing when warmed up from running. test draw when first started and after running for amount of time that it usually quits, and if noticeable difference, motor is seizing and needs replace. You can also test amp draw at main 120v feed wiring with unit just in fan mode.

Why heater fan will not come on?


Wish I knew how old your furnace is. Let me answer your question directly. In the heat mode the fan runs independently from the air conditioning fan relay. Its either brought on by time or temperature. An old furnace will use a fan and limit control that uses a coil to sense the heat exchanger temperature and turn the fan on or off. Newer furnaces use a timer on a circuit board. 20 years or newer Ill bet its a timer board. Follow the blower motor wires back to the component and ill bet that's the culprit. Hope it helps. Good luck.

Heater fan not working


Smack it and see if it comes on. If it does then the motor brushes are bad. If it does not come on, check the fuses. If the fuses are ok, check the voltage on the plug to the motor.

Goodman package heatpump blower motor contant running


check your themostat fan mode switch to see if it in on or auto. It should be in auto. If this does not stop indoor fan motor, (it may take up to 2 minutes for the fan to stop, preprogrammed shutoff in the thermostat and fan control cards may make you think the fan has not stopped ) If this does not stop the fan the fan control board in your air handler has a green wire shorting to 24 volt signal in the theromostat wire or the contact on the blower control card is stuck and will need replaced.

1993 Ford Escort Blower Motor & AC Switch


I'm going to start from the beginning.
The blower motor gets power from the high blower relay and it is grounded thru the fan switch and the resistor. So you should have power on the pink white blower wire coming from the high relay to the blower motor. The orange black wire from the motor is ground going to the resistor and fan switch. The blue wires on the control panel are for the ac compressor.
The high blower relay gets power from fuse number 5 in the box. The blower motor is grounded thru the resistor and then thru the fan switch.

Model TWEO36C140A1 blower will come on if I throw the breaker switch...but thermostat doesn't seem to be in sync. Fan will run in "on" position and once blower is running, in auto. ...


If no relay I'm assuming this is an x13 motor. Try swapping speed taps 4 and 5. It's possible the winding is over heating. Tough one to diagnose without being there. With power off take pic of tstat wiring and remove all wires. Be sure to spread wires apart to prevent blowing fuse. Turn power back on. Red and white together should bring on heat and fan. Red green and yellow should bring on fan and compressor. Try this several times each way making sure the blower comes to a complete stop every time. If everything seems to work by bypassing tstat you likely have a bad stat. Provided swapping your speed taps was unsuccessful. Good Luck!!

Blower motor will not come on. i have a rheem furnance


Turn your fan from auto to on at thermostat, if fan doesnt come on.
Remove blower motor door to get to control panel-Turn poweroff !
Try to turn blower wheel to see if it will turn freely,

Remove thermostat wires from control board, put a jumper wire between
r and g.Put door back on and restore power, fan should run. If it does
than it is possible you have a burnt out speed on whatever cylcle heat/cool you are trying to use.

To troubleshoot this-turn power off and find where the blower wires go to
control board. exchange the wires from park to heat or cool terminals.
put cover back on and restore power.IT should work,if nothing happens then you probably have a problem with blower

Bottom blower dose not go on


you should have two wires that go to a capacitor for turning the motor the right way durring start up then you should have two wires for run current. Now my motor has red and blue as the run voltage and blue and a white wire to the capacitor -6uf+/-10-5%@250AC. This cap is mounted on your fan shroud and refer to you top motor wire configuration, as both blower motors is in like the same wire colors to cap. Now my lower motor keeps blowing the thermal fuse and dose not overheat as the thermal needs at least 360 degrees of heat to blow yet my moter when running is not that hot.... I would replace the motor and cant seem to find one where did you find yours.

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.

Blower won't kick on


My guess is the FAN RELAY has loose contacts in it Trace the wires from the motor to where they tie in 1 will go to the power cord (this in L2 or Nut) The other 1 or 2 wires will go to a fan swich/relay or a rotary hi limit fan acutator sw. This rotary fan sw has a lot of cousins. On some Carrier Bryant Paynes and or Day Night furnaces that are over 20 years old the fan switch is a small rectangular cube with a seperate heater inclosed in the rectangular box. This fan sw could also be your problem but Im betting on the fan relay. It usually Click when you turn the Fan from auto to on. And the wire G goes to it (eventually)from the thermostat. CHeck this when its acting up. You could jump around the relay going from the L1 feed on the relay to the Closed motor speed.

I doubt you have a bad fan motor. But I could be wrong. Usually they have a smell associated with a bad one and you dont mention this.

No high speed on blower motor


if motor works on heat, but not on cool ,then the low speed is energized by the heat strip or control board .if the motor doesn't run in high on cool, then the fan relay or black high speed tap from the board is not being energized. usually its the fan relay ,which is only a factor in cool in high speed fan mode. try turning fan to on at stat. that energizes fan relay and blower should run in high. gently tap the side of the fan relay and see if fan comes on all of a sudden. if it does the relay is bad. change it wire for wire label all wires and use exact replacement relay unless you know how to read wiring diagram then you can use a 90-340 generic fits all replacement. trace motor power wires back to relay or control board to find where they are fed from.
