The reset button is a 15 amp breaker.
One possibility although remote, is that the reset breaker itself is broken. Is the switch loose, or does feel like it makes the expected switch, just the fireplace doesnt come on?

You have tried it in a different AC outlet if the plug is movable?

More likely though, it is something shorting within the electric fireplace, and it is tripping the breaker as a safety measure, as soon as you turn it on. Sometimes you can hear this, if you turn it on and it immediately turns off and trips the breaker.

Either way, this should be looked at by a qualified repair person, as you do not want to mess around with defective electrical circuits in your home.

Dehumidifier tripping AFCI - DoItYourself.com Community Forums

Oct 1, 2011 - My dehumidifier is on a 15 Amp circuit with an AFCI breaker. ... What I mean by that is that it can run without tripping for days or only a few hours ...

The circuit breakers may both be functioning properly. What might be happening is that both circuits have other current drawing appliances on them. The circuit breakers react to the sum of all of the currents drawn by all of the devices on that circuit. So, if you have a 15 amp microwave and an 8 amp refrigerator on the same circuit, you would overload a 20 amp circuit by 3 amps.

Turn the Master On/Off Switch to OFF and unplug the unit from the wall receptacle. Leave it unplugged for 12 - 15 minutes. That should give it enough time to reset itself. Then plug it back in and give it a try. Also, make sure that the wall receptacle is working properly and hasn't tripped the circuit breaker in your home's circuit breaker panel. If it did, something is seriously wrong electrically, with the heater.

Hope this helps you solve the problem. Please don't forget to rate my response to your question.
Thanks!

Not an unusual problem with any electric fireplace heater. I suspect the overheat circuit has shut the heating element down. Or the element has burned up (that's not unusual either).

In any event, turn the fireplace OFF and unplug it. Wait 30 minutes before plugging it back in. During that time, the overheat circuit may reset itself. If that fails to solve the problem call The Technical Service Dept of Dimplex USA at 888-346-7539, Monday - Friday, 8:00 a.m. - 4:30 p.m. EST. If it ends up needing parts, you can order them at that time.

Have the Model # and Serial # of the fireplace, handy. As you will need to provide that information to them, as well as the date of purchase.

Sounds as if the Fan Switch may also be faulty. Or the new fan motor is defective. Is the flame function on the electric fireplace working? If the flame function is working, than obviously the fault is either in the fan switch or the new fan motor.

If the motor has a regular receptacle type plug on the end of the cord, try plugging it directly to a wall outlet and see if it works. If you're able to do that, then the problem is in the fireplace's fan switch or in the wiring circuitry going to the fan motor. Perhaps, this is what was wrong all along and not the fan motor, itself.

If nothing is working, check the wall receptacle that the fireplace is plugged into, by plugging in an electric lamp. If the lamp won't turn on, then there's a circuit breaker tripped in your homes circuit breaker panel. Check the circuit breaker panel for a tripped breaker and with nothing plugged into the offending receptacle, reset the breaker. Plug the fireplace back into the receptacle, turn it on and see if it trips the circuit breaker. If it does, there's an electrical short some where in the fireplace. Look for burned or frayed wiring, as well as bad connections.

Hope this helps solve your problem.

There is a safety bi-metal strip that is probably tripping out. Does it turn back on after a cooling down period ?

I would not go to larger breaker size until I knew why 15 amp breaker is trippingIf you find out that 15 amp breaker is tripping because it is being overloaded or that breaker is getting weak. Then I would replace breaker with the same size because they may have wired some with 14-2 wire instead 12-2, I would not feel comfortable pulling 20 amps, on 14-2 wire. That is my suggestion for what it's worth. Thank you.

heater is drawing to many amps for the heater to run correctly check the circuit it is on and possibly move to a different location on a circuit that has more amps from panel box.
