    My outside a/c unit runs, but the blower motor in my furnace does not. The blower motor is good. The control module indicator light flashes 1 time indicating a system lockout. Is there anything I can reset or look at? Or could the module be bad? (amana) Thanks

Hi, there are different reasons why a furnace fan will not run.

It may be as a result of a blockage due to built up of materials on the furnace fan. Switch of the furnace, take the cover off and check to see if there are any thing blocking it.

The thermostat may also be faulty, try fiddling with the thermostat dial unit you find a place that the fan will cut in at. You need to change the thermostat......

Lack of power can also be a problem, check to see if the thermostat of furnace is switched on, although this is an unlikely cause but could happen. check the wiring connection and if you cannot see any loose wire, call in a tech.

Loose wiring, if found that there are loose wiring around the furnace, call in an electrician to fix it up.

And finally, the fan itself may be faulty/bad and needs replacement. Only a electrician can determine this..

Take care

Is the furnace/air handler fan running? If it is not, then, check to see if the fan on the outside unit is running. If the fan on the outside unit is not running either, check to make sure that the breakers for the furnace/air handler and the air conditioner are on.
If the breaker is not tripped, then the problem may be your thermostat, the furnace/air handler control board, or the wires between the furnace/air handler and the thermostat.
If your unit has a condensate pump, check to make sure the reservoir is not full. If the reservoir is full, a limit switch will normally stop the air conditioner from running. You will need to repair or replace the pump.
If the breaker is tripped, you can reset it by shutting it off and then turning it back on. If it trips again, then check the wiring in the furnace/air handler for signs of damage and repair as necessary.
If the blower is running but the fan on the outside unit is not, then continue your air conditioner troubleshooting at the outside unit.
If the blower isn't running but the fan outside is, the problem could be the blower motor, its run capacitor, or the furnace/air handler control board.
If the blower on the furnace is running, check to see if you see any frost or ice around the units. You might also notice water around the furnace. Is there ice on the copper lines going outside? If yes, then shut the outside unit off for a couple of hours but let the blower on the furnace run. This will allow the ice to melt.
After two hours, you can continue your air conditioner troubleshooting. Turn the ac back on and let it run for about five minutes. Now feel the larger copper line at the outdoor unit. This should be cold and have condensation on it. If it is not cold or if frost is forming on the line, it is probably a Freon problem. You will need to call a repairman because of federal refrigerant usage regulations.
If there is no ice or frost, then continue troubleshooting at the outside unit. If the fan motor is not running, then shut the power off to the unit. Then check all wire connections for signs of damage such as burning and repair as necessary. You should also check the wire connections in the compressor terminal box and repair if necessary.
You can use our capacitor testing guide to check the unit's capacitors and replace as necessary.
Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

    Thanks for responding. The outside unit runs fine. My inside furnace blower motor is not. I momentarily applied power to the motor and it ran. I get 1 flash from the diagnostic indicator light on the control board which means system lockout (Amana). Can anything be reset?

    The reset can be done only at circuit breaker.If only the power is coming and going or the unit shuts off in between.But as per the problem which you mentioned it indicates the fault in the module that has to be replaced to clear the problem.
    Thanks for keeping updated with your query.

I've got a Air condition unit model BV124 30-10L16, which is the part of Lennox furnace unit. The indoor fan stops working now. The outside fan works fine. I checked the capacitor, fine too. Cooling...


Hello, a blower motor will not run for one of theese three reasons 1) No power to motor 2) bad capacitor 3) the motor itself is bad. One test you could do is take the wire of the L1 terminal on the control board and use a jumper wire and connect it to the wire on the high speed motor tap , if this gets the unit running then the control board must be replaced if it does not work then the motor is shot......make suremwhen disconnevting wires the power is off.

No power to ac indoor fan motor


sounds like you might have a bad control board. try putting a jumper wire on the control board low voltage terminals R and G your fan should come on and run if you have 120v power to fan motor. double check that you do have 120 leaving board and going to motor. if no 120 bad board if you do have 120 bad motor. if it is the board it likely has a bad blower relay which is common in amana models and goodman equipment.

My AC unit wont blow the cold air.


if the ac outside is working, but not the furnace, means there is a control problem with the furnace, check wires in the furnace, make sure there is a blower wire plugged into the contact marked cool on the control panel of the furnace

Fan and heater run fine but fan does not shut off for a long time


Check the diagnostic indicator.
1. If the blower runs for hours make sure the fan switch on the thermostat is set on "auto".
2. The furnace safety system must be in lockout. This is the furaces way of telling you there is a problem.
3 Most common problem is a dirty flame sensor.

Furnace won't stay running


1
1 FLASH
Furnace fails to operate.
• Integrated control module
diagnostic LED is
flashing ONE (1) flash.
• Furnace lockout due
to an excessive
number of ignition
“retries” (3 total)1.
• Failure to establish flame.
Cause may be no gas to
burners, front cover
pressure switch stuck open,
bad igniter or igniter
alignment, improper orifices,
or coated/oxidized or
improperly connected flame
sensor.
• Loss of flame after establishment.
Cause may be
interrupted gas supply, lazy
burner flames (improper gas
pressure or restriction in flue
and/or combustion air
piping), front cover pressure
switch opening, or improper
induced draft blower
performance.
• Locate and correct gas
interruption.
• Check front cover
pressure switch
operation (hose, wiring,
contact operation).
Correct if necessary.
• Replace or realign
igniter.
• Check flame sense
signal. Sand sensor if
coated and/or oxidized.
• Check flue piping for
blockage, proper
length, elbows, and
termination.
• Verify proper induced
draft blower performance.

Ruud achiever 90 plus blower not working


does the furnace ignite?? your system may not have been lighting and has gone into ignition lockout count the codes of the led lights then remove panel led diagnostic codes are listed there.
if led codes indicate no problem verify capacitor is good and that mtr is getting 115 volts.
