Answers :

Check the fuse for the blower motor. It may have blown. If that's not it, it may be the damper door in the heater box itself is stuck closed. Not sure if that model year damper door is operated pneumatically or electrically. Hopefully, you still have the Owners Manual for the car. That should help determine which it has.

Don't panic, but I have a question about my 40 year old duo therm RV roof top AC. I know, it shouldn't be working, but it does. My problem is it will kick on, compressor starts to work and puts out cold air, then I hear the relay kicking out and it stops putting out cold air. This past fall I took the shroud off and cleaned everything and observed the operating system. Again, it starts, runs for a minute or so, than the relay opens. If I push on the relay, it will run again. A friend suggested a


When you say relay I'm assuming the contactor. Does it shut off again when you let go of the contacts (relay)? Most likely it's low on refrigerant and the low pressure switch is shutting it down. ... Dometic Rooftop RV Air Conditioner

Hello i have Carrier Weathermaker 38tkb air conditioner unit. It's about 6 years old and when i got home today, the unit itself wasn't working. Although the blower fan in the furnace inside was blowing, the fan on the a/c unit outside was not moving. I can hear a humming sound coming from it and once in a while, you hear it trying to kick in (the lights in the house even dim a bit, which is unusual), but it never kicks in. The top center of the unit is extremely hot to the touch. I've checked


The humming noise and dimming of the lights is an indication something in the outdoor unit is locked up or has failed.Check the capacitor as it may have gone bad. If the capacitor is good, then you either have a failed motor, a failed co ... Air Conditioners

My indoor fan comes on but the compressor does not. I checked voltage, fuses and wiring and everything was ok. When I depressed the contact (single pole) the compressor would run and make cold air. When I did it a second time it held in and ran so we cooled the house down. Thinking the contact was bad I got a new one but it wouldn't come on but would run if I held it in and would shut off if I let off of it.. It has control voltage to the coil on the contact. The contact just wont kick in or sta

The compressor in my central air unit does not kick on. Sometimes it will sometimes it won't. I really notice when it doesn't because of the scorching heat from outside. Basically when the air is off all night, which I don't run at night because it is to cool, but in the morning when the thermostat is set for it to come back on the compressor won't kick on for a couple of hours after if at all. Please help me figure this out. I'm pretty handy a do it yourself projects.

I thought i smelled the ordor of burnt wire coming from somewhere in the house, which I could not figure out where it was coming from. I tried to regulate the therostat and found the a/c would not come on. So i turned off the unit for a few minutes to turned it back on and all i could hear was a loud humming sound of the motor, but no air were coming out of the vents. The outside fan is moving. I wonder what could be the problem.
