I was called out for a no-heat on an electric furnace today. A different company was there yesterday but according to the customer the system did not run last night. The customer tried to contact the other company but evidently they don't answer the phone on the weekend so the customer called our company.
The first problem was a failed transformer which I replaced. Before operating the furnace I checked for any other problems. The other company had replace the blower motor with a sealed case condensing fan motor. That surprised me. The specs on the motor were correct for the furnace but I have never seen a condenser fan motor used for a blower. In the interests of doing the job properly, I replaced it with a blower motor.
Would the use of a condenser fan motor be okay? The only objection that I can think of is that a blower wheel is heavier than fan blades.
What do you guys say?
