My unit runs for about an hour then the circuit breaker on the unit trips and won't reset

So, only use it for half an hour at a time, let it cool down, then continue with the project. Mine didn't over heat.

Not sure what is wrong with your unit but I have the same one and all I do is hold the middle button for 4-5 seconds and light turns off completely.

My unit ran on batteries for 6 months and is still running. There is no ac connection

Yes, it sounds like you are in need of a new logic board. It's not your batteries because its working in your garage. Suggestion, if your unit is more than 10 years old, I recommend just spending double the money you would spend on a logic board and replace the unit in whole. Once the logic board is in need of replacing, the other parts tend to want to give up as well.

I started having the same problem with mine. I think the unit needs to be returned.

If the breaker trips then the element is defective. The thermostat module may be bad. Masterbuilt customer service is pretty reasonable so give them a call. Also try a different outlet perhaps your ground is bad. Good luck!

If it's blowing the breaker (or fuse) regardless of which circuit it's connected to, the problem is most likely in the heater itself. I would have it serviced by an authorized dealer.

since it is intermittent it sounds like you may have a load (that is not always on) connected on the timer line side. The timer side needs a dedicated path. Also, you may want to check and make sure that the voltage on the line side matches the voltage you set the unit to.

Haven't had this problem myself. Try taking the batteries out for a few mins then reinsert and see if that will reset the unit.

Our parent unit power switch just failed too! Ours is just over 1.5 years old as well. Now I'm browsing these questions to see if anyone has found some solution... Sounds like a product defect.

You can reset it after power went out by unplugging it and plugging it back in. Or trip the breaker on the circuit it uses and reset it.

There's a small reset button in the back of the unit that you can press to restart the unit & if that doesn't work, it may have a blown fuse...

Make sure you have a 120 volt supply line not 240 volt. If you have the correct voltage then make sure the timer disc is properly seated which I suspect you have done, then it is probably a faulty timer.

Try the reset procedure--unplug for 10 minutes. I've not had this problem with this model.

Sounds like you tripped a circuit breaker at your electrical panel. These units can require their own fuse breaker because of the power they need.

I doubt if many/any of us have tripped the breaker, so you might not get a solid answer. I've been using two of these for 18 months or so, and have never pushed them that far (nor would I recommend you try to run &gt;15 amps). But it's a circuit breaker, not a fuse, so you should just be able to press the reset button (after reducing the load, obviously!) Hopefully you'll get someone to answer who's actually tripped the breaker, but in absence of that, I wouldn't be concerned about it; that's how a circuit breaker works.

I am sorry I can't help, as I also faced the same issue. The moment I powered up, the fuse trip and the whole unit is down
