I have the Dayton G73 Utility Heater which will be mounted near the ceiling in my garage. The ceilng is at 12 feet. Can I move the thermostat from the main unit and mount it to the wall, or install another on/off control so I can controll this without being on a ladder.

If it sounds like the fan is hitting something, It is likely you will have to get a step ladder, and look closely at what is making the noise-
Likely something fell in there-- and needs to be removed.

When you shut the thermostat down, does the fan stop instantly?

Where can i find a thermostat atc-26b l57c 5813-11002-00 for my Dayton g73 heater. Any help would be appreciated. Can find anything info of course lol

I WOULD TRY TO BYPASS THE THERMOSTAT TO MAKE SURE THE UNIT WORKS AND REPLACE THE THERMOSTAT IF IT DOES , SEE IF IT IS UNDER WARRENTY, MY GUESS WOULD BE THAT IT IS JUST DEFFECTIVE, AND YOU ARE TRYING TO FIND A CAUSE, THIER IS NO REAL CAUSE THAT I CAN THINK OF THAT WOULD BURN UP THE THERMOSTAT IF IT WAS OR HAS BEEN WORKING, GOOD LUCK

Are you getting 240 volts to the heater? The heater should react to thermostat instantly.

Its probably trying to tell you something is wrong with me.. find the root cause!(like the fan motor is stopping and then the heat builds up and tripps the high limit switch!

Yes, but it will require some knowledge of electric to do that. You will need a line voltage thermostat and mostly like have to have that run a contactor that will be wired to bypass the heater thermostat. A good electrician should be able to to this for you very easily.

This is a good application of this type of heater. There are many things to consider as you size the heater though. Insulation, 1,2,3-car garage, insulated garage door, average ambient temp. etc. In most cases of garage heaters, they are used to temper the air from cold to a workable temperature. If this is the case, I'm sure this would take care of most applications of garage heating.

your best way is get all thread rod and cut to size

These heaters are the same as the marley heater, the element never gets red hot. the unit is set up so the fan kicks on after the element has heated to a certain temp and turns off after the element has cooled. It is common for these heater fans to cycle on and off quite often untill the air temp reaches about 55 degrees and then will operate normaly. If the fan still cycles too often you may have to replace the fan control and high limit switch. These are not very expensive and easy to replace yourself. they arte usualy attached to the back of the element with clips. The luke warm air is what these units put out. I have an equivelent to the dayton G73 and it heats a 24' X 30' garrage all winter in central Minnesota.

How many amps is your service? And what gauge wire did you use for the heater?
If your service is only 40amps that is your problem. You don't have enough amps for the heater and the rest of your house, you will have to upgrade your service.
