    Reseting the limit switchs located near the heat tubes will solve this problem.

SOURCE: have a coleman 5640 heating/cooling

Yes, to change from heat to cool is done by reversing the power plug that is close to the housing. Matching the blue on the plug(as I recall) makes it cool. The red to blue makes it a heater. If it is currently heating, the unit works fine, it just needs the polarity reversed.
Good luck,
Glenn

SOURCE: Rheem Criterion II air conditioner runs but it does not cool

Check air temp out vent should be approx 20 degrees colder than room temp if it is your unit is too small for the amount of space you are cooling.Rule of thumb 1 ton(12,000btu's) for every 400 sq ft of uninsulated space

SOURCE: My Rheem central A/C blower motor cycles on & off

Depending on age of Rheem they have a time delay relay. May be causing the problem. The time delay operates the fan. Try turning fan to continuous and see if it stays on.

SOURCE: Amana Cooling Condensing Unit fan stops spinning after 15 mins

Capacitor, dirty condencer coil causing the motor amps to run too high. But most likely worn bearing on blade side of motor causing it to pull to one side causing it to over heat and shut down. Sleve bearings should have no side play.

My Rheem Criterion II gas furnace makes metal slapping noise when the blower comes on. It is not the blower or the motor.


Is there noise when the inducer motor comes on? The small motor that comes on first. It sucks the co out of the combustion chamber. It comes on first. Then the burner lights then the blower comes on. And the noise continues while it's running and doesn't stop till the blower stops? Is that correct? But it's not the blower wheel? Could it be out of balance and hitting the blower shroud?

Replaced Thermostat and now Blower Motor will not run


Sounds like a set up issue on the tstat. You say this is a packaged unit, inside the machine you should find where the tstat wires hook up. Typically red is power yellow is compressor orange is reversing valve white is emergency heat green is blower. Put red and green together, test blower. Then red green and yellow, make sure blower works again. If blower runs both ways it's either the tstat wire or tstat itself. Make sure you are landing wires on dedicated heat pump terminals, make sure in settings you are set up for heat pump with back up electric heat and TSTAT CONTROLS THE FAN. Good Luck. Also if there is a switch on the tstat for gas or electric on the back you want electric.

Rheem condenser fan don't spin up under it'sown power.


If you have a multimeter that tests "uf" or "mfd" that is microfarads. That will test the capacitor. Turn off power to unit, touch top of cap with insulated screwdriver across terminals to discharge and remove fan and common. MARK WHICH WIRES GO WHERE. Or if no mfds on multimeter, amps×2650÷volts=mfd. Amp draw on fan wire off of cap times 2650 divided by the volts between common and fan on the cap. If cap is good it's likely the motor.

You need to check the wiring to the limits and safety devices with are in a number of locations, make sure all connections are tight.The most common cause for the blower to run is the high limit device which is the one mounted above the burners on the flat metal panel with two wires.

When the unit is turned on. I can hear the AC pump kick on and run. But the blower fan motor will not turn on at any fan speed. No setting on the AC will get the blower fan to turn on?


Sounds like then fan has died or the run capacitor has die. All motors that run on single phase mains need a capacitor to start them spinning. These are quite cheap & simple to replace usually - worth just replacing if you feel you can't test it. Looks a bit like a 'D' cell battery with 2 leads hanging out. Could also be that the unit is not cooling/heating and the temp sensor will not activate fan until heating/cooling coolant has passed room temp. - Rick

Rheem gas furnace blower unit not working properly


look at circuit board and follow wires that come from fan motor, if this is a standard motor black is high and it will be going to a prong that says cool, red is low and it will go to heat, you will have a yellow and a blue that are "parked" remove red park it were the blue is and put blue on heat, if this is a variable speed motor you will have to set dip switches via your equipment manual

A/c/heater blower will not work


Does the motor get voltage when it is supposed to be running. You need to take a volt meter and see if it is getting voltage. If it is getting voltage than it could be a bad motor. Also, if it is getting voltage check the capacitor and see if it test to what it is rated to be. You will need a capacitor tester to do this. And if it is not getting voltage to the motor when a call for cooling or heating then it is a fan control board or relay. Depends on what controls you have. Hope this helps.

Rheem A/C unit makes a clicking sound when


Shut down the unit and turn the power off. Take the cover off of the blower housing and feel around within the squirrel cage. It sounds like something may have been drawn up into the blower. Also it is possible that the blower wheel might have thrown a balance weight and caused the wheel to become unbalanced. It could also be the motor about to go out but since I can't hear it myself, I'm trying to cover all the bases.
