Question about Carrier Heating & Cooling
When i turn the unit on at the thermostat i hear the click that indicates power has been supplied. I go outside and the unit sounds like it is fixing to explode. It sounds like a tea kettle when it is time to take the pot off the stove, very loud high pitch sound. The blade does not turn by itself or with help. I must add that the unit is 21 years old.
Hey there, sounds like the bearings seized in your fan motor. You need to replace the fan motor. If the compressor runs without the fan, th pressures build up and if they reach an extreme point, the compressor will bypass internally, creating a loud sound as the high pressure is released to the low pressure side. I would turn the thermostat on and stand by the outdoor unit as it start. Leave the disconnect on the wall readily available so you can quickly turn it off. If the compressor sounds ok when it starts up and runs for a couple seconds, turn it off right away and replace the fan motor and you should be good to go. If the compressor sounds bad or real noisy immediately at start up, the fan motor not working killed your compreesor. You would need a motor and compressor, might as well replace the unit at this point if you are paying to have it done. Let me know if you need anything else
