How do I know if my roof air has heat strips too?

My 2002 American Eagle T-Stat has dual zones and HEAT/AIR plus AC/GAS options. I figured I could run HEAT/AC (vs HEAT/GAS). The roof units do kick on but no heat. How do I verify that they have a heat strip?

With our Bounder, the thermostat has an "elect" & a "gas" mode. However, if I set the mode to elect but the temperature I set on the thermostat is greater than 3 degrees above the registered temperature, the elect won't come on. The gas heat will kick in first to heat up the interior until it's within that degree range, then the gas will shut off & the elect will turn on. I don't know if your thermostat control works the same, we are both Fleetwood units, but I thought I'd throw this scenario out.

Also, the elect will not heat if it's too cold outside (below about 38-40 degrees). It just blows cool air, if any. The heat pumps can't extract enough heat out of the air to provide heat inside my coach.

Your Eagle has a/c heat pumps rather than electric heat strips. They give a modest amount of heat as long as the outside air is above about 45 degrees. It takes several minutes for warmish air to flow.

If the a/c provide does not heat, it could be that the reversing valve in the a/c is not working, but the odds that it failed in both a/c's is infinitesimal. A thermostat problem would be more likley.

Gary,

I would find it hard to believe that they wouldn't install the "heat pump" or "strip" in my MH. I pulled out the instructions for the T-Stat and I programmed it as the directions stated having a separate Air Conditioner and Furnace. By doing this, it took away the Heat/AC option on my T-Stat. I have the MH in my driveway tonight (It goes in tomorrow for Duo Blinds) so I will reprogram it to get the Heat/AC mode back. I think you are correct regarding the outside temp being the issue. (It's 18 degrees right now)
