The FHWH112WA1 combines cooling with electric heat, which adds heating elements and safety limits to the usual window unit layout. A short burning-dust smell on the first heat run of the season is common, but a persistent burning odor means the unit should be switched off and unplugged right away.
If cooling works but heat does not, the heater element, thermal limit or control is tested. Heat mode draws a lot of current, so breaker trips should be checked by a professional rather than reset repeatedly.
