I attended a demand call for Dale in the Cochrane area, during my inspection on the main furnace I found the inducer motor to be exceeding rated capacity and layered with dust in the windings which poses a partial fire risk. During my inspection for the garage heater I found the flame sensor readings to be weaker than optimal reading to engage the control board. I have provided the customers with several options and h fortunately the main furnace is no longer being manufactured along with its parts. The customers have an HCA going out Monday to provide quotes for a new furnace.
