Review on Electronics Salon SPST NO Module Control Voltage by Mike Carter

Although the oven switched on 24 VAC hot/cold supplies the required mA, the relay quickly burns out after only one switching operation. I ran 115VAC through com and NO respectively and in parallel and in theory this should have allowed the fan to run on hot or cold cycle. It ran in the cold but as soon as I checked the heat cycle I smelled burnt electronics and quickly identified it as a relay. Again, DO NOT BUY an oven to change the built-in fan.
