Having problems with your Air Conditioners ?

Blower fan runs at one speed - very low

\015 I just had a Amcoraire UCHW-H12AF2 uni installed and everything seems to work OK but the inside unit blower motor. It runs at one speed only and that is very slow. I had the contractor recheck the wiring and that all looks good. Can you help with this problem?\015

Blower fan runs at one speed - very low


There is a sensor on the indoor coil that needs to reach a certain temp before the fan speed will increase. Sounds like the unit is undercharged if the sensor isn't reaching the temp it needs to. ... AmcorAire UCHW-H24AF2 Split System Air Conditioner

I think your run capacitor for the blower motor needs replacing. \015\012If it goes out the motor will not develop full speed and will shut off on it's internal thermal protector. When it cools off it will kick back in until it gets hot and shu ... Air Conditioners

This is a heating and cooling through the wall heat pump. It works normally when heating is selected - the heat pump runs and both speeds of the fan blow warm air. But nothing runs when cooling is selected. In other words the unit works normally when "High Heat" or "Low Heat" is selected but nothing runs when "High Cool", "Low Cool" or "Fan Only" is selected. The position of the Fan Cycle Switch has no effect - behavior of the unit is the same in both positions of the Fan Cycle Switch.

I have a Dometic rooftop Air conditioner in my RV When I turn it to low medium or high the fan run the same speed and when I turn it to AC it will run for about 5 min then the fan will shut off but the compressor keeps running I turn it off for a min or so and everythings comes back on. Turn it to the fan only side and the fan will run for 5 min then shut off a min later it comes back on then back off and on in fan only side.


Bad fan motor I suspect The windings are bad causing the motor to over heat sending the motor into thermal overload. would suggest the replacement of motor. Good Luck on repairs\015\012\015\012Dave ... Dometic Rooftop RV Air Conditioner

I. The outdoor heat-exchanger fan runs at a low speed (with a humming noise), when the home temperature is below the set-point. ii. When home temp. in high, fan runs at full speed, like normal. iii. When A/C breaker is shutoff (in main switchboard), the fan stops. Need help diagnose the problem.


It could also be the contactor; basically an electrically-controlled switch that in turn controls the compressor and the condenser fan. If it's a 220 volt motor, and one side of the contactor has very high resistance, it'll be seeing 110 volts inste ... Air Conditioners

My compressor unit outside runs and cools Freon but the inside blower has a problem running. the model # is 2TEE3F31A1000AA. The fan control, in fan run control mode, shows a bright green for the fan LED and the CFM selection LED varies with the rotational speed of the fan. The motor tries to start showing , initially, a jerky back & forth movement. It squeaks some and may, or may not, start rotating. If it starts the CFM LED goes bright/on no flicker and the motor runs briefly (5 seconds) then


Hi, from what you have told me, you are loosing the bearings in this blower motor along with windings. This motor is rubbing the blower housing, tight when you turn it, and when it jerks when it tries to start tells me that you have burned or very we ... Air Conditioners

I have a rheem electric furnace with 2 speed fan, seems like the fan runs full bore when its on, even when i just cycle the blower control to ''on'' and its supposed to run at reduced speed. I have to experience with central heating and air, was wondering if it would be the circuit card with the dip switches. Unit was installed in 2003 with a heat pump.


If it is a variable speed blower most likely the dip switch settings. Check the installation manual to see how to slow it down. ... Air Conditioners

After a power outage and surge, I tried to run the carrier high efficiency furnace "FAN" only to circulate air in the warm house. when I stated the blower, it ran on slower spped than normally.usually cycles between high and balst furnace high....now its running slow.I tried the heat cycle and the blower speeded up a minor amount over just with the fan circulating....is there an internal circuit breaker that could've beed bitten with the surge??

When I press the button to change the speed of the fan it does nothing, and continues to blow at one speed and it is just about equivalent to the speed of the slow option...any ideas why?
