    nope overheating of the motor would not have caused the board to go power surge bad grounding ligthning and directly shorting it would cause that the board should be protected by 3 amp fuse

ASTA12JCC Inverter system coming up flashing LED error


could be the evaporator capacitor in the evaporator that has gone bad.As long as the motor in the evaporator is free to spin ,more likely the capacitor is defective . Its normally on the logic board soldered in place ,between 1-2.5 uf 450volts (rectangular black looking thing with 2 leads)

I have a Amana unit Model# PGA60C1152F that has a blinking light on the control board it blinks 4 times. That heat will come on then go off but the blower nevers comes on.


look on the inside of the door that you took off and there should be a diagram and on that there will flash code that will tell you what 4 flashes means.i think it is a flame rollout or high limit.

Where do the 3 wires from the blower motor connect to on the control board for high speed use in the summer time? Black, Blue, and the Red one? The white is a no brainer. I can go to M1, cool, and heat....


Hello, the black wire is your high sped motor tap and it should be on cool as you have it. Blue is med-hi and red is your low speed motor tap. You have it wired correctly. Now the freezing can be caused by 2 things, low airflow or a low refrigerant charge. Low airflow can be caused by a dirty air filter, dirty evaporator coil, dirty blower wheel or the blower itself is running slow due to a weak capacitor. Anytime the motor is changed out the capacitor should aswell. If the airflow appears to be ok then the unit is low on refrigerant.

Trane xr12 blower stays on after first cool cycle run


Hello, this is usually caused by a sticking fan relay on the intergrated comtrol board. You may be able to tap on it to shut it off but eventually the control board will need to be replaced.

Carrier gas heater


You may have a defective control board or blower motor. You will need to find on the main control board the location where the blower motor (marked heat) is connected. Using a volt meter, after resetting the limits and restarting unit, you will need to check and see if the board is supplying 1115 volts to blower motor (between the blower heat terminal and one of the neutral terminals on board). Also have someone hold in the door safety switch, or put a piece of tape on the switch, The switch will pop out when the bottom furnace door is removed, this is the normal location of control board. As the furnace goes through its normal cycle and prior to locking out on safety (limit opening) you should get 115 volts from the board (terminal marked blower / heat). If the board does not put out 115 volts, then the board is defective. If the board puts out 115 volts and the blower does not operate, the blower motor is probably defective, there is one more check to do. Close the door and put your system in cooling, see if the motor starts, if it does, then the low speed (reactor) is defective and motor needs replacing. If the motor does not start in cooling mode, you may have a defective capacitor. Check all of the above first and see what happens. Good luck, and be careful.

Have a rheem 90 plus gas furnace the problem is that when you call for cooling the indoor blower does not come on. On the control board there are 2 green lights and one orange light. The top green ligt is...


At your thermostat turn the fan from auto to on, if the blower motor still does not come on, down at the furnace remove the blower door, turn power off first. Locate the blower motor leads, switch the cool lead which is usually black with the blue wire which is usually medium high.
Make sure while you are at it to see if the blower motor will turn by hand. Put door back on turn on power, leave the fan switch to `on` still. Blower should turn on. If not then either the blower motor is either burned out or you have a line/lolw voltage wiring problem.
You did not state if the outdoor ubit was operating, that will make it easier to troubleshoot.

Trunthe fan from the automatic position to the on position, if the blower does not come on then you
might have a relay problem. The relay is built into the
board, you may have to replace the board.

Run a wire from the sensor down to the control board conector. Bypass the sensor wire around the connector in the blower deck.
The connection can be wire nutted on the sensor lead with the wire (16 or 18 guage stranded wire works) routed through the blower deck to the other side of the plastic wire connector on the blower deck.
The Sensor operates at high voltage but very low current. The connector will sometimes fail due to humidity or wear.
I have seen this on the Rheem or Ruud furnaces.
Hope this helps.
