My parts came in, I talked the dealer into giving them to me to install so I don't have to have the hassle of an appointment and hauling the trailer to them to leave it.

It took me about 15 minutes to swap out the control module. Unfortunately we are have a very abnormally warm weather pattern right now and I can't test it until our temps get back below 40 degrees.

Here is the label on the box I was given.


Parts in the box but you will only replace the black module box.


You will need to get on the roof and remove the 4 Phillips screws and lift the cowling off of the AC unit. I then carefully separated the foam box housing the fan and control module. I was able to grab the two places shown by the arrows to gently pull to separate.


The arrow shows the location of the module. It is held down with strong double sided tape. I used one hand to hold down the gray box while pulling up on the module.


I noted the module I removed had the #2 toggle switched so I made sure the new module switches matched the one I removed.


While putting everything back our wonderful mouser climbed the trailer ladder and joined to supervise, lol.


I will wait to go back up and put new double sided tape on until I can verify it works below 40 degrees but all works perfect right now.
Hi there, does anyone have the part number to order from trekwood for this? I have a fuzion 419 with three ACs. Which AC unit would this part be in? thanks

My dealer couldn't figure this one out either, and he's a "professional."

You can buy an aerosol can of "freeze spray" -- or if you have "canned air" (computer duster) you can turn it upside down and get the same effect. Just spray it on your temperature sensor and you can make your thermostat think it's as cold as you want. To test your air conditioner, use a hairdryer instead.
