The front AC unit in my 95 has had Thermostat problems for a long while, I was able to get a friend to resolder the on/off switch on the board, but when it failed again there was no hope.
This thermostat is no longer available and Dometics answer is to replace both the control board in the roof unit and the thermostat at a cost of about 300 for parts. This did not seem logical when that is almost 20% of the cost of a new AC.
Thru a website RV-Coach.com and a fellow FT owner I was able to contact a William Hendrix in CO. For 85 bucks plus shipping he was able to repair the board of the thermostat and turned it around in one week.
He also will work on 4 and 5 button Comfort Controls.
I have no connection with him other than being satisfied with his service and prices.
How about a link or some contact info. ? ??? I may need him/this company some day... :)
Gerry, The way I found this was through RV-Coach.com , on the discussion boards about electrical issues. I never did have a phone # for Hendrix, just his Email whendrix@aol.com.
I had my 4 button thermostat repaired by Dinosaur Electronics in Lincoln City, OR. Works great now. About the same price.
Mr Hendrix still rebuilds them & can be contacted at whendrix@aol.com
"Yes, I rebuild Dometic / DuoTherm thermostats and I can also provide upgrade kits to the current 5 button style with instructions."
"We travel so it is best you contact me by email before sending -- some times it is not the thermostat
but my present address is 370 Baker Lane, Erie, CO 80516
Regards, William Hendrix"
Biggest mistake I made was replacing old energy hungry Coleman units with modern energy efficient ones in an attempt to get my ATS from opening frequently when using both. The old ones were so much colder and cooled down the rig almost instantly. The new CFC free stuff is not as good as the freon. Do what it takes to keep your old ones going. I should have rewired from generator to ATS and put in a relay type ATS and kept my dinosaur AC units.
