We carried our 2004 Fleetwood Southwind to Motorhomes of Texas for repair as the heat is coming on and off even when the thermostat is off.  It also does it when the A/C is on.  They said that they could not find a thermostat as they were not made any longer and sent it to a company to be fixed. It is an Intellitec Electronic Climate Control for duel A/Cs. P.N.-C07-0350.  We paid $2300.00.  We took it out for the 1st time and it still does the same thing.  The supervisor over the repair department is not returning our calls.  Does anyone know anything about the thermostats?  We cannot find the Intellitec PN-C07-0350 but we see the PN-C07-0330 which will not work on dual units.  Just watched a video on Youtube and it confirmed that it is the thermostat that is the problem. Anyone know where we can buy a new thermostat as the referbished one still does not work.
