Question about Goodman CKL24AR24 Air Conditioner

1 Answer

The model number as listed on the receipt is CKQ24. The Blower moter in the air-handler is not running. When the fan-only switch is turned on, the blower motor will attempt to spin by pulsing for about 2 seconds. It will repeat the pulsing cycle in about 2 second intervals. There is no smell of burning. When the unit is set to AC and auto, the evaparator coils do chill. The blower motor is a variable speed motor with an external ECM. How do I test the ECM and/or motor? What should I look for in resolving the problem?

Personally I would get an exact replacement capacitor same voltage rating and microfarud rating. The capacitor will read something like 370v 5uf. I would be surprised if that's not the whole problem. If not it needs an exact evaporative fan replacement, and the new Capacitor. Happy cooling!

Carrier electric furnace (air handler) stopped running


The 5 amp fuse may be bad, they go quite often, and they are exactly the same as the car ones. Check the fuse with a meter. If its OK turn the unit on and check for voltage going to the blower fan. You should get a reading between at least one pair of wires. The unit should have a schematic on it somewhere, check it to see which wire pairs are used for the variable speeds of the fan.

Check fuses first! If yours is the model with a fuse box you will see a flap that pulls down to reveal a block of fuses, the blade fuse you described is part of it too! Are all fuses ok?

I have a Ruud heat pump/air conditioner. The out side fan and unit works fine and cools fine but now the inside fan that blows the cool air in will not turn on. We can turn the fan with our hand so I don't...


You didn't mention if you checked for 115 volts at the power supply to the air handler. The unit outside has its own power supply. A lot of times the switch that is on the wall doesn't like to work after its been turned off and back on for service, also check the blower door safety switch. If the blower door hasn't been put back in place properly and snugly it will kill power to the whole air handler. Hope this helps. Good luck

My air handler comes on ,not the outside unit when my thermostat is in the off position even if i turn the thermostat down to 50 and have it turned off the air handler comes on for about 5 to 10 minutes...


If you have a standard thermostat the fan switch is for the air handler only. It completely over rides the thermostat for most settings. Now lets see this is what I'd expect:
fan switch on Indoor fan runs all time
Fan switch auto Indoor fan only runs when thermostat is set to cool or heat and the thermostat is turned up above room temp for heat or below room temp for cooling. In both of these modes the furnace blower comes on and stays on til the room temperature is satisfied. The outdoor unit only comes on for AC the out door unit will not come on for heat or the "on" setting on the thermostat. See exception 1 & 2 below...

Exception 1- (in a heat pump the out door unit runs in both heat and cool mode unless it has emergency heat turned on then it will not come on outside in the heat mode, and depending on the type of heat pump and furnace or air handler it is). A heat pump thermostat usually has "backup heat" and an "emergency heat" setting switch on the thermostat.
Exception 2 - On some thermostats they are made to cycle on the heat if the temperature reaches a preset temp (around 50'f usually but definitely by 40'f). This mode prevents freezing when if instance the homeowner is away or while the home is under construction. In this mode the fan inside can run but the heat usually comes on with it.
Exception3 - On some electric furnaces the heating strips may be individually controlled and thus not all come on at one time. This may give the feel of no heat especially if the room is cold.

Now there may be other exceptions but Ive tried to give you a heads up on some of the most common ones.
If you need more help please post more specifics about your unit/system as to for sure what switches are set to what setting and what is happening with each. My first though was that maybe your system is OK and you needed to know if the thermostat was working properly.

If this helpd you understand your problem would you please give me as hifgh a mark as you can. Thnaks for using fixya and good luck.

Is EDF5 required to have intermitant running of Fantech HR 2005R?


The SHR2005R will turn on the furnace Blower if the furnace is not running to circulate the fresh air. The reason the furnace will not trun on the HRV is, the purpose of the HRV is continuous Ventilation in your home. It should not be turned off when your furnace is not running. That why Fantech has not design the HRV's to run that way. I hope this helps.
