Camping in WV this last week got a little cool so turned on the heat on the Carrier A/C unit and it was not working-- but it did work last winter. Opened the unit up today and checked the voltage going to the heat strip, was ok. Checked the heat strip with an ohm-meter, it was an open circuit. Pulled the heat strip out and noticed it has what appears to be a thermal cut out switch that cuts power to the heat strip if it overheats. It does have a reset button on it (not mentioned in the A/C users manual), reset and back in business.

I have a theory that it may be best to turn the temperature control to cool and let the heat strip cool down before turning off the fan on the A/C unit. This may prevent the thermal cutout from tripping again -- time and use will tell.
