Need to look around and should have an error code and give more detail of what the problem is. If you post that i can maybe help you more. I need to know......
Awning retracts at random
some awnings have a sensor that retracts the awning if wind elevates to certain level. i wish mine did. i have seen them ripped off rv's.
Replacing a duotherm 3105058 thermostat
I was replacing a DUO-Therm 3105058 Rev A. very old Thermostat in a Coachman RV with 3106995.032 from Amazon. After looking all the information on the directions it was clear I would have to play a hit or miss on some of the wiring. Instead of using the same coding, such as RC, RH, G, Yellow and such. they used the function and I had to guess at some.Here is the wiring I found worked:There are 6 wires. One set of two wires (white On the W & red on the RH) and the set of 4 (yellow On the Y, green on the G, red on the RC and blue on the H). So to keep it simple the red on the RH went to the +7.5. The White on the W went to the FUR. HS/HP not used. the Yellow from the Y went on the cool. The green on the G went to the fan. The red on RC went to GND. and the Blue on H went to Hi fan.So red (RH) of the 2 wire goes to +7.5White (W) of the 2 wire goes to FUR.Yellow (Y) to coolGreen (G) to fanOrange or red from the RC lug goes to GNDBlue (H) goes to Hi Fan
I need an electrical wiring diagram for an rv air conditioner. Dometic model QC135-A.
So original was ecm and you’re installing psc?? All low voltage speeds will go away and you just need to break the new, high voltage speeds, with a relay. Hope that helpsI can’t find info on the 135a. Does it have a control board to land wired to?? What model motor???Can’t make out the original wiring diagram. The white is your common or neutral. The different speeds are for constant fan speed, cooling speed, and heating speed, this is your hot. Not sure if you have a control board in your unit but if you do it will say “common/ fan/ cool/ heat/ park for places to land your wires. The browns go to capacitor and the orange and purples would get swapped if it were running backwards. ( meaning blowing air out of filter rather than pulling air through filter. Zip tie loose wires to prevent getting caught by wheel.
Need advice wiring new motor into old Dometic a/c unit.
On a single phase universal motor with a start and a run capacitor, that is handy.
The start capacitor is fully automatic as there is an internal centrifugal contact that breaks the contact when the motor reaches near running speed.
The run capacitor puts one of the motor windings out of phase with the other and determines the direction. Placing the run capacitor on the neutral will make the motor go the other way than on the live.
My rv air wont work on high?
could be the selector switch turn off power switch low and high wire if it blows high replace selector switch if it does not work replace motor. Tom
