I'm working on an 15 yr old wood furnace it has a dimer switch and 3 clicks on censers the blower that supply's air to the fire won't come on I need to know what does what? Dan

Please restate your request. I cannot understand what you are looking for here. If a motor is not working you need to test the motor and the motor circuit with a meter to find out what the problem is.

The unit is a Jensen about 15 years old my friend bought house about 7 years no paper work I've relapsed the dimer switch the fan center is working OK I'm looking for wiring diagram to tell me what the 3 clixons are running and what temps they are

I have no diagram for that name of unit. In fact here is the USA the only thing with that name is a jansen richmond water heater and there is no master parts list for that either. Sorry.

The klixons you are talking about are available in all temperatures and settings. Just look on them and the settings will bw listed either stamped on the metal or printed.
