A Canadian North Boeing 737-200, registration C-GOPW performing flight 5T-228 from Yellowknife,NT to Kuglutuk,NT (Canada) with 4 passengers and 4 crew, was climbing out of Yellowknife’s runway 34 when the crew smelled und subsequently observed smoke on the flight deck and suspected, the smoke was related to the captain’s side window heat plug. The crew stopped the climb at about 14,000 feet MSL, worked the related checklists, unpowered the side window’s heating and the smoke dissipated. The aircraft returned to Yellowknife for a safe landing on runway 16 about 40 minutes after departure.

The Canadian TSB reported maintenance identified a faulty window heater.
