Coleman Mach Air conditioner fan problem???

[jolooote]

Hi all. 2015 Thor Vegas, 15K BTU AC. All worked B4 I started work. Just got done cleaning the roof Ac fins. Removed roof plastic cover, Removed tin sheet metal cover over the Evaporator? fins. Cleaned em. Put all back together. Now, got nothing when indoor thermostate is on FAN, any position, Auto, Manual, Fast or lo. But, When in the AC position the fan runs in only the LO position. The compressor runs in both Lo and HI. WHAT have I done?:?
Shoulda listened to my dads advise. "If it ain't broke ...DON'T fix it!"

If you fixed the problem by "wiggling" the wires, expect it to return.

[jolooote]

Yep, wiggled those wires, works now.

First on Colemans you do not need to remove the sheet metal cover to clean the condenser. Colemans suck so the crud collects on the OUTSIDE and all you need remove is the outer shroud.

Sounds like yo knocked a wire loose but how you did that I don't know as there are no wires near the area you were working on

Check all plugs and connections.

This should be your first clue You disturbed some wiring at the A/C. Got water into some connections? Knocked some wires loose?

Whether the fan runs or not is controlled by a relay. It probably has a center off position and either switches to high or low depending on what's selected on the thermostat. I could be more help if I knew the brand/model of the a/c so I could find a wiring schematic.

opps, I'm in 'Roads and Routes'. Thout it was Tech. Issues. Sorry.

Nope. Maintenance is important and necessary.
