My fan in the bathroom is constantly running no matter what position I put the switch to.
The switch looks like this:
And there is some other controller that I don't understand what it does (never used it before):
Can someone please tell me, how is it possible that the fan keeps running even if I put the switch in the off position?
Is it probable that it has some internal sensor and that sensor turned it on?
Also, did someone see that "Thermolec" controller before and can point out to me what it does?
This is the model of the thermolec controller:
And this is the fan case (sorry I can't get to the fan right now because my hand is broken. I'll need help):
Thanks in advance for your kind help.
P.S. There was a power outage insident recently. A lightning strike hit the house and there was no electricity for 3 days in the neighberhood because 2 transformers were blown out. That's when the problem started.
It might be a coincidance because a real brutal heat wave has also arrived at the same time and the electrical generator that the State Electrical company has put infront of my windows doesn't help with dissipating heat. lol
Best Answer
The thermolec is a make up air duct heater , the lightning strike may have damaged the control board is the occupency sensor causing the fan to run as long as there is power. I would turn the breaker off pull the controller (switch) and disconnect its power if the fan stops you know where the problem is the switch. If the fan continues to run with the power restored and the switch disconnected the thermolec duct heater may be controlling it and that would be the next item to remove power from the controller (with the power off). I would guess the occupancy sensor part of the switch failed.
