Coleman Mach AC fix

[@stonehenge11]

This was the issue for me. Fan woould come on when I just turned ONLY the fan on. When I turned it on to cool...ALL went dead. IT WAS THE BLUE WIRE! - Thanks Man!!!

[@JennerJ2103]

This worked for me! I turned a/c and breaker off, reached up from inside and wiggled all the cords. Turned it back on and could hear it kick on. So happy!! Thank you!

*Love this unit! Using upstairs in my sons bedroom **Fastly.Cool** and he’s finally able to be comfortable upstairs without me freezing downstairs. Works for more sqft than expected!*

Finally, my A/C is working again, after 2 day trip I knew it must be some loose cables somewhere. I was able to access them from inside the RV. Thank you so much! Sweety toddler and mom thank you!

[@glen2392]

Thank you! I just had the same problem. Mobil tech would take a month to get on his list so I checked Utube and came across this. Saved me a month of sweating.

Thank you for posting this fix. My Coleman Mach AC did exactly the same thing. Once I open up the top cover it fired right up. I cleaned all the terminals and it is now working . Thanks again!

[@gregwoods6640]

Thank you for the instruction! Loose wire was exactly the problem! AC working just fine again. Saved me trip to dealer 😁

[@joechandler8398]

Thanks! A loose connection in the same place stopped mine from working on a warm Christmas Eve day. Mine was the yellow wire.

I found that my issue was similar, but the main wiring harness had come loose. Thanks for this video!

[@ramonmedrano7462]

Man, Thank you for this. Found the same problem on mine. I was right about to give up.

[@Maxwedge8263]

Thank You for making this video!!! I went through my ac and after replacing the capacitors. The compressor started working again but now my ac isn’t cooling the camper. I checked the lines and the top ones are freezing up. The air coming out inside is the same temperature as outside. All the filters are clean. I’m just wondering if I need to get it recharged.

Hi i have a coleman TSR in my caravan when i turn it on theirs nothing no sound or anything any ideas what it could be will i check to see if power is going to it or do i spin the fan

[@ooocodyy2575]

Thank you!! That’s exactly what it was! When I touched it it started cooling right away! Thanks for the info!

[@dablingtime]

Thank you

I just now figured out mine. Thermostat. Pulled from wall and no 12v out of the yellow wire with cool set to on. Turned the fan on and unhooked the yellow wire and shoved it into the incoming 12v to the thermostat and bingo. Compressor kicked in.

[@youlag814]

I am really hoping I have the same issue I already installed a new thermostat and a new capacitor with no luck

[@jvietri]

Me too. Was just about to give up and Presto!!! Thank you so much.

[@Fortsmirhsmiths]

Thank you. My camper won’t do anything. The only inside controls are the thermostat. No fan no click. Nothing . Maybe I should try removing the cover up top?

[@robertboyd3863]

Same as ,my problem

[@beengreen9803]

FYI. U got mold on your insulation. If u are smelling it through your vents it may be from that. I replaced mine and no more smell. Hope that helps

[@Hiperf]

I have literally the exact same problem. Been fixing it and giving up year after year. Mine will sometimes fire right up! The next time will be quiet and then suddenly fire up randomly between 4 - 30 minutes. The time after that it won't do anything. Last fall I had a fan issue and just replaced all 3 of my capacitors. Fired right up twice without issues. No today it's back to not starting. About ready to set fire to this stupid thing.

[@Hiperf]

Just took the filter cover off and reached up into the wires. Mine look like they are the push in style. Rocked the crap out of all the wires and the box itself and it did nothing for me. How do you jump the thermostat

[@Hiperf]

Was able to hook the yellow wire to the 12+ red. Fired right up. Bad thermostat.

[@stewartboy]

Yes sir thank you for this video!!

[@Fortsmirhsmiths]

Can’t figure out mine. No fan no click

[@TRKVSports]

Theres the problem a broken blue wire...thank you

[@kurtiwaniuk]

Hopefully this is my issue! Nope! I guess it time yo swap capacitors

[@Mysailingvacation]

You had the camera on the evaporator core when you were talking about some piece of phone flopping around so we don't know what you were talking about. Also you didn't mention or maybe you should know that if you had corrosion on that connection when you moved it back and forth you should put some corrosion protective on The wire even fluid film or oil a grease or Vaseline to prevent further corrosion making your connection bad again it's good to spray all your connections to prevent them from being corroded in the first place.. decent video just prove it first before you post it you would have seen that your camera was not showing you flop your foam around

No help at all
