Replaced the blower motor on a Carrier a/c unit x421892 after motor seized and tripped breaker. New motor runs fine but runs continuosly when put in the auto position.

Need help for Toyostove vented heater- Laser 56MH heater comes on when thermostat sensor calls for heat. It brings room up to correct set temperature and begins normal shut down. But here is the problem...the circulation fan stops and I think the blower moter stops? But fire remains in the burner chamber and a moter is quitely running...I think it is the exhaust? The only way it will completely shut down is when I turn back the temperature selection 10 degrees. It immediatly shuts down. Then
Hi, there is a problem going on here, and its not the unit it self, but in the control circuit. From what you have said as to how and what is taking place is, the control thermostat works on a call for heat and cycles down when the desired temperatur ... Air Conditioners
Blower keeps running even after thermostat is in off or in auto? The forced air unit stays on even after temp setting is reached or will switch thermostat switch to off. The heat stops but blower stays on until I turn the breaker off.
This could be an indication that there is an error code flashing on the control board and needs to be addressed. Most newer units like this indicate a problem by running the room air blower to alert the homeowner something is wrong. Really! Without s ... Carrier XHB123D X/Y Series Heat/Cool Air Conditioner
When I turn the air conditioner on, the indoor blower runs for about 10 seconds and then stops. After which the red fan symbol on the evaporator section blinks and no condenser. I don't have any fault code legends for this product. TAS-24H

I have a carrier 38YCBO48300 Over the years ithas a history of eating the start Caps Which I replace myself. This time the cap was leaking so I replaced it but the unit still will not run.The blower runs but not the outside unit. there is power and I hear a click when the system is turned on if I push in the relay the unit will start. but stop when I release it. I have checked the float switch in the condenser pan Any other ideas??

The motor or blower wheel om my Goodman model GMP 100-4 unit whistles and sticks. How can I fix this? Can the motor or blower wheel be lubricated? Does the motor need to be replaced. If I manualy spin the blower wheel and get it turming some what and then start the unit by pressing the safty switch located behind the lower front panel the blower will start, the wheel fan will turn. If I turn the unit off and try to turn it on again before the wheel stops turning the blower will work. But, if

I have a Goodman Furnace that doesn't turn on. If I spin the blower it will run, blower just buzzes and still buzzes while running. It shuts itself off after twenty minutes. I can resets it and spin the blower and it will turn on again.
First I would suggest that you replace the start capacitor on your blower motor but if it is running for awhile that makes me wonder if the thermal overload is shutting your motor off. You can replace the start capacitor and then if it starts as it's ... Goodman CLQ24AR42 Air Conditioner
Turned on AC was running fine. 30 minutes later began to hear a strange noise. Opened AC/Furnance closet & heard a sound best described as air letting out of a tire. It seemed to be coming from copper pipe. Minute later sound stopped & air was suddenly hot. As if AC was turned on fan not cold. Went outside & neither fan nor motor was running. Turned fan manually. Ran for about a minute then stopped. Outside unit was making what could best be described as a buzzing sound.

The fan in my Heil air conditioning unit runs for a while then stops turning. When I turn it off for a while and re-start it it runs. Is there a way to lubricate the fan. The motor is running but the fan stops.

I have a problem with my heating system. It is about 10 years old and has had the ignitor, combustion blower motor, and programable thermostat replace in it's lifetime. The system worked great last year. This year has not been so good. The system was checked and cleaned last month. What is happening is the blower kicks in and the burner cut off after a few (15-20) seconds. I tried shuting down system and turning off power to reset.

Janitrol (goodman) GMS9. Two years old. When thermostat is set low the ICM diagnostic LED is continuous on ("no signal from thermostat"), when thermostat is turned up then LED gives 3 flashes. Manual says that 3 flashes means "Pressure switch circuit not closed. Induced draft blower is operating", however the ID-Blower is NOT running. I ran a 110Volt wire directly to the ID-Blower to see if it runs independent of the control and it does run. I drew vacuum on both pressure switches and they do

The blower in my Ruud gas furnace won't shut off. It just runs and runs. The thermostat is set to "off" and the fan switch is set to "auto". We haven't used the furnace or AC the past few months since we haven't needed it, so it's been in the off position. Then yesterday out of nowhere the blower randomly fired up and hasn't turned off since. It just runs and runs until I kill it at the breaker. The thermostat is about two years old so it's fairly new. I replaced its batteries and that didn't
