Hello all.

I don't use it often but the electric heater function in the AC unit stopped working. A quick look seems like the unit needs to be disassembled from above? If anyone has done this (heater element or thermostat) or has youtube link, much appreciated.

Jake,

 

The heat strip can be accessed from inside the trailer, it's mounted inside the return air duct.. The 2010 models have a troublesome, hypersensitive, overtemp switch that has to be manually reset when it trips..

 

To access the heat strip. First start by dropping the filter grate, this will expose the mounting screws for the ceiling assembly.. Start the ceiling assy. removal by removing the three phillips head screws in the blue discharge duct, then remove the four phillips head screws that retain the ceiling shroud to the inside retaining plate..

With the shroud out of the way, the heat strip will be visible in the large opening mounted just in front of the evaporator coil.. Reach up and press the reset button on the over temp switch located on the top of the box where the wiring connects to the heating element..

Here's a pic of the heat strip removed to show the location of the overheat switch.. (note: this is a pic of an early model heat strip with the auto-reset overtemp switch)

Contact Little House Customs for a permanent fix.. Larry has the OEM auto-reset switches that Coleman installed prior to 2010..

 

Hope this helps..

OK, I'll bet lunch-for-a-month that your problem is with the over-temp switch.  Step-by-step Instructions for a 'fix' is here: https://www.casitafo...s#comment-52314

 

You can do it, and no work from the roof!

It's been 5 or 6 years since I replaced the manual reset over temperature sensor in my 2008 with an auto reset over temp sensor. I don't remember having to remove the 3 phillips head screws in the blue discharge duct. I do remember having to remove  very strong and sticky grey electrical tape from inside the blue discharge duct. It seems like the tape was acting as a seal to ensure the cold air would be directed out of the discharge duct.

Had to remove and replace my electric heater to install a digital thermostat and it was fairly simple and as described above.
