SOURCE: Wiring diagram needed RV rooftop coleman

Motor1258,
Thanks for the response, to be more specific, the nine pin connector was damaged, but I was able to connect the wires back to main unit panel. I am ready to hook to the hunter thermostat and do not know which wires to connect to. This is my problem and I do not want to short something out. Hope this helps, I want to get it installed again. Thanks again for caring....Jerry

The clicking is normal and is caused by the thermostat attempting to activate the compressor to come on. Since neither the fan nor compressor runs when the switch is turned on, then it appears as if the electrical power is not getting to the RV AC unit. Check the breaker panel to be sure the power is going through the breaker and on to the AC unit first. In some cases the breaker will appear to be good but is not allowing the electrical power to pass through.
It is possible for the electrical connections in the ceiling panel assembly to be loose or the wire nuts may not be tight enough. If all of these connections seem okay the control switch itself may be shorted out.
A multimeter is very useful for checking the connections and switches for proper functioning. If you still cannot trace down the problem, please feel free to ask for further info. Let me know if you find the issue in the electic supply if not we can start to trouble shoot the system. It is not uncommon for a breaker to kick when unhooking and hooking back up to an electric system in a camp park.

What wires coming from the theromstat conect to which wires coming out of the wall


suggest this: hire a technician to fix it for you. you would need the wiring diagram for the thermostat and to find which wires go where in the wall.

this is a task that is normally beyond the ability of an owner. It requires some technical knowledge of thermostat wiring, as well as using a voltmeter.

you might post an ad to locate another owner of your model RV, then ask them to pull the thermostat off the wall and take some pictures to send to you - showing the wiring connected.

regards,

I have a coleman evcon gas furnace I want to change the termostat to a programmable thermostat I don't know where the wires hookup we have four wires red,white,yellow,green. I have a honeywell RTH230b...


The thermostat has terminals which are marked for color, R = red, W = white, Y =yellow, G =green. There should be a jumper between Rh and Rc, Hook the red to Rh.

I need wiring manual for goodman mini split.


outside unit L1 and L2 are load (input 240vac)
then you have control voltage, usually yellow and blue (24vac) this connects to some 18/2 thermostat wire which goes inside as white and red.

note: this unit may only need 24v control which is 2 wires from the inside unit and also 3 wires 2 hot 1 ground for line voltage.

STANDARD WIRING
on the inside unit you have green, white, blue and red control wires.

on your thermostat you have white, red, yellow and green

you run the wire from the outside unit to the inside unit. then run a 18/4 wire to the thermostat if wired and join the following wires.

inside unit thermostat outside unit
green------------------------green
white-------------------------white
red----------------------------red
blue-------------------------------------------------------blue
yellow--------------------yellow

I have a travel trailer with a roof top a/c colman mach111 and I hooked up a thermostate digital. The heat works but cant get a/c to come on. the termanials on hunter thermostate are G W Y RC RH


OK, the wiring that you should have in your RV is as follows: Red White Blue Yellow Green Gray.

This Thermostat will not work on this Air conditioner because the tstat you are installing is a 24V thermostat. The connections are as follows G = Fan, W = White, Y = Cooling, RC = 24V Cool, RH = 24V. The only thing that I can think to do is hook it up like so.

On the G Terminal, Hook up the Green wire from the wall. On W, hook up the White wire, Y, hook up the yellow wire. RC = run a jumper from the RH terminal, RH = hook up the red wire. If this doesn't work then you will have to go back with the coleman thermostat.

What's the deal? Wont shut off or respond to thermostat. . .


Red= power........White=heat.............Green=fan.................(grey)-(yellow)=cool .....these are the connectons. Disconnect these wires from the thermostat and know that red/power is the only wire that send power to the thermostat, and the rest sends it back to the unit to call for whatever,, red--to . white for heat... red to green for fan .... &red to grey for cool! OK! Turn all your power on, and use a jumper wire from red / green for fan and see if the fan comes on! Then move the jumper wire from red to green , to red / to white for heat and the fan , wait for 3 minutes before removing and going to the next step. Then red /to grey for cool and check if the outside comes on. Either you have a wire touching past the insulations and making a connection, a bad thermostat ,oe excessive wire lead touching the next connection.Thank you very much!
