For those of us that have the Dometic 4 button thermostat, you can replace the switches for less than $10.00. You can actually take the switches apart, replace the contacts and reassemble. I just ordered my switches from Mouser Electronics, Inc. under p/n PVA10AH2. They were about $1.22 for each switch and then around $5.00 for Priority shipping from the Post Office. I'll let you all know how it works out. I already had one of the switches apart. Doesn't seem like its gonna be a problem. If anyone is thinking about attempting this be aware that there is a very small spring that will pop out when you take the top off.

DONE DONE AND DONE!!!!! The switches that I ordered came in yesterday. It took about 5 minutes to replace the defective switch. My fan switch stopped so I couldn't toggle between zone 1 and zone 2, I can now!! The fix was cheap and very very easy. Forget about buying the reconditioned ones. I had one person say he had some for $150.00, others on ebay had them from $155.00 down to $60.00. One guy was reluctant to sell me just a switch but said he would for $15.00. I found a post at www.irv2.com website that listed the manufacturer part number and found a supplier that sold the switches for $1.22 each. I got for switches and priotity shipping for $9.95. The thermostat works like new.
