Blower stopped working, any ideas?

[Yarzy]

Hi everyone, I have a blower fan I got when we purchased our Jotel Oslo about 3 year ago. It stopped working and before I call up and order a new one, I wanted to see if there was anything I might be able to do to revive it. I took it apart last night hoping to find a fuse and there was nothing. Any ideas on how to get this working? It does not come on with the theromostate or the manual switch.
Thanks!

Could be the snap switch (thermostat). If you are careful and understand motors a temporary test would be to bypass the thermostat with a jumper. If that still fails I would directly wire the motor, bypassing the both the switch and thermostat. If it still fails to start, then the motor is dead. You might want to take it to a motor shop in that case to see if it can be rebuilt.

Thanks! So, I have a question about what you suggested. I think I know how to bypass the thermostat, I can just run a wire between them, right? The issue is, my switch has both an auto setting (thermostat controlled) and a manual, both don't work. I am wondering if it is just the switch that died out. How do I go about testing this? I know you mentioned wiring up the fax without the switch which makes sense, but how do I do that? Thanks so much!

Try jumpering the thermostat first. Odds are that's the problem. And remember these are high-voltage connections. Unplug the fan before starting and tape temporary jumper connections.

ok, I will try that tonight. Do you think the thermostat could still be the issue even it I had the switch on manual? I would have thought it would have bypassed the thermostat. Thanks again!

Good point. The best way to check is on manual is to test the voltage at the motor. If it is live (120v) then the motor is the problem.

Is there a way to wire it up in a temporary way to bypass the switch? I am not sure how to check if the motor is getting power with a multimeter.

It's simple if there are only 3 legs on the switch, but without having a good picture or at least a schematic of the switch I am hesitant to recommend this because I would prefer it to not have a shocking conclusion.

May sound like a silly question but is there power at the outlet? Electrical motors usually give some kind of warning when they go. Either the smell of burning plastic or loud operation (not always though). BG is correct that if it has 3 wires its a simple test. A photo would help tell you which wires to test. Multimeters are cheap and I don't ever recommend jumpering wires unless you really know what your doing. Electricity can do a lot of damage in a hurry if you short it (nothing to fear just respect it).

And no offense to you but if you don't know how to test with a multi meter you shouldn't be jumpering wires.
