Description of Problem:

It has been determined that installation of the thermostat models subject to this bulletin (model numbers noted above), only if attached directly to a supply fan electromagnetic contactor may demonstrate overheating and /or smoking as the result of a cracked capacitor (see Figure 1 for example of this connection). The load introduced by the equipment contactor coil could fatigue this capacitor on the thermostat’s Equipment Control Module (ECM) printed circuit board resulting in electrical overstress and excessive heat.
