There's a pattern we've seen in South Lake Tahoe mountain homes: heating systems that quit during winter usually aren't broken. The thermostat just stopped talking to the unit. Got a call about this property where the owner, out of state at the time, heard from their cleaning service that the heat wasn't working. When our technician showed up and got inside the cabin, the Emerson thermostat read 52 degrees. Way too cold. The gas stove unit had a good pilot light going, but the thermostat had lost its calibration settings. Power fluctuations are common at this elevation, and that's probably what did it. After recalibrating the control system, everything checked out fine. The thermostat and heating unit were talking again.
