SOURCE: heat strip installation

It was quite simple, just installing the heat strip and my model only required removing the grill cover and mounting the element. The other optional installations didn't apply to my model.

thanks,
Don

SOURCE: will not shut off

Sounds like a stuck relay on the unit itself. Maybe there is a short in the control wire that comes from the thermostat that activates the fan.

The thermostat probably has one hot wire at all times. The thermostat then chooses which wire to send the voltage down based on your selection. One of those wires is probably for the fan only. Make sure that it is in good condition (no bare, pinched or wires)

SOURCE: RV ac is vibrating

Take a good look at fan blade for a crack in one or more, as well as turn unit on & watch for vibration , then take a look at mount bushings on all items. Also with fan off (obviously) check shaft for movement, side to side, up & down, in & out. Your gasket between roof should only be compressed approx half it's original thickness. Some manufacturers tighten them down too much and can be a source of vibration as well. Not expensive or hard to change. Don't forget blower wheel as well.

SOURCE: Dometic air conditioner blowing cool air

When the cooling slows down, but water is still running off, usually something is icing up. You can turn the unit off, and let it thaw, and try again. Sometimes, if the humidity is high, this is more pronounced. It sounds like you are low on refrigerant. That implies that you have a slight leak. You should have the unit serviced, and the leak repaired.
Best regards, --W/D--

SOURCE: Duo-Therm AC bearing noise

Yes, it sounds like your bearings are bad. If it is cooling, then you know the compressor is working.
The only other thing really, would be the motor.

1999 VW Passat AC/heat doesn't work? The belt broke this summer? I was told should still blow heat even if no belt?


If you are talking about the belt for the ac compressor, yes the heater should still work.
If the blower is not working, you will need to have the blower motor checked for voltage and ground.

fill your radiator, if that doesn't fix it then your heater core is most likely dead.
