2000 roof-top Brisk-Air

To use the electric heat on your 1988 Mallard Sprinter travel trailer, you will need to follow the instructions for your specific Duo Therm Brisk Air unit. Here are the general steps you can follow to use the electric heat:

1. Set the thermostat: Set the thermostat to the desired temperature. The thermostat controls the electric heat and determines when it will turn on and off.
2. Turn on the electric heat: The electric heat on your travel trailer is usually controlled by a switch or a button on the thermostat or on the unit itself. Turn on the electric heat by flipping the switch or pressing the button.
3. Adjust the temperature: Use the thermostat to adjust the temperature as needed. The electric heat will turn on and off as needed to maintain the desired temperature.
4. Turn off the electric heat: When you are finished using the electric heat, turn it off by flipping the switch or pressing the button.

If you are having difficulty using the electric heat or are unsure about how to operate your specific Duo Therm Brisk Air unit, you may want to refer to the owner's manual or contact the manufacturer for assistance. They will be able to provide you with specific instructions for your unit and help you troubleshoot any issues you may be experiencing.

loss of 120 volts to relay module

No service ports on the unit. It needs to have a service port soldered to it and the system breached before you can check / charge.

my rv has one unit that acts as if its pulling sewer gas off roof while running some time worse then others.

Yes the air should be drawn from the trailer, over the cold coils and then
back into the trailer, whether rear or front.
The condenser coils should be self contained on top and blow
warm air outside the trailer

well check a few things first....have someone remove the cover and reach in with a hand and try to manually spin the blade...free spinning?....then tell the person below to click in the on postion while someone views from up top.....is it humming? or even trying to spin?....if not check the fuse on the RV that protects the A/C unit.....good?.....now replace the capacitor ( it the silver or gray can looking thing that the motor wires run to) only the correct size will work w/o causing further motor damage.

Turn the ac off go up top the coach and remove the cover. Look for fan blockage, Wasp, mud dauber etc. Caution if it is wasps they will chase you off the end of your coach. Take some spray with you. If there is no blockage the fan motor is toast.
Thanks for using Fixya

1The air coditioner does run on Electric. 110V 2. No you do not have to unhook the battery 3. Yes you need to put water in the hot water heater so you do not burn the unit up.

First of all, I think you mean 110 volts on your meter, not amps, just so we're on the same page. It sounds to me like you may have a capacitor problem on your compressor. I'll try to see if I can find you a part # if you have someone very experienced with electrical that can change it for you. they can be a little dangerous, so only someone familar with them should work with it. What the capacitor basically does is store voltage and uses it to help the big draw on start-up of the compressor, kind of like giving it a boost to get it started, and after it's up and running, all should be well if everything else is up to snuff. How old is the AC unit? Did it run well for you in the past? I'm asking this just in case it was a recent installation, with perhaps wrong size wire used. Should be minimum 12/2 , with 20amp breaker,if that means anything to you, or your mechanic.

Either your 14"x14" a/c gasket is lose on the roof allowing the condensation to flow into your RV or you have a cracked condensation tray under the evaporator. I'm guessing the later
