A 40 ohm reading on the AC heater is within normal range, so the heater isn't the trigger. Icing with a new thermistor usually means the power board isn't shutting the heat off (a stuck relay is common). The Dinosaur N991 power board fits the 9182 and has a 3-year warranty. First, make sure the thermistor is clipped to the correct fin.
