SOURCE: Dayton G73 electric heater

I just got my G73.  It comes with a new note that says "below 50 degrees the fan will cycle randomly (and might seem like its not working correctly) but once it is above 50 it will cycle normally."  it uses that to let the element re-heat quickly to bring the room up to temp faster.

You should be able to google the manufacture and look for a contact us area where you can get a hold of them and order it unless the part is obsolete. They could have a universal replacement.

SOURCE: dayton 175k heater

the air pressure is not correct on either units.the photo cell DOES NOT look for light any more,it count the light flashes.if the flame is not in the right possition the heater will shut down....after the unit ignites the ignitor is no longer used to keep the unit working,just the fuel that is being fed to the flame ball.that's why the pressure is so inportant.......

SOURCE: Dayton Furnace - Pilot Light Goes Out but Fan keeps running?

Pilot lighted furnaces have a thermocouple made from disasimilar metals that when heated create electricity to actuate a relay that alows the gas to flow to the furnace.

When the thermocouple gets coated with carbon from the pilot lights constant burning it acts as an insulator and keeps the thermocouple from getting enough heat to generate electricity, a very good safety factor.

What you have to do is locate the thermocouple it should be located over the pilot light, you will see a gray substance around the thermocouple it will be hard like cement, take a knife and scrape away as much of the gray material as possible then sand the themocouple with a medium sandpaper until it shines, use one of you wifes emery boards, this should solve your problem.

My incoming voltage is only reading 200v, will this stop the unit from running??


If it needs 208 or 220 then yes it will stop the unit from running.Check the voltage at the circut breaker to verify its not a wiring issue.

You may need to get a new circut breaker.Also check a 115 volt outlet if its is also reading low ,like 100 or 105 volts then the power ccompany is cutting power back and theres nothing you can do.

Hi, I have a Dayton 3ug73 heater. The heater will not shut down after the initial heat requirement is met. I have the thermostat set on low but it continues to heat. I shut the power off to it to keep...


It sounds to me like your thermostat may be bad. I would check power incoming to t-stat then turn temp. setting up and down to see if it is switching on and off. If not then replace. If it does then I would check all wiring to gas valve and if power is shutting off to valve but burner continues then replace gas valve. Thank you.

The heater operation is very noisy compared to new. Perhaps it's the fan? The heater is six years old and I'm concerned that it may cause a fire.


Its most likely the bearings in the fan motor failing causing vibration. One simple way would be too check and make sure all nuts and screws and bolts are tight around th e fan. If so is the fan blade dirty it doesnt take much dirt on a fan blade to get it out of balance and cause bearing failure.

Hello,
You want to use the 10/3 wire... the red and black are the hot, the white goes to the nuetral and the green/bare wire to the ground.
Use a 30 amp 2 pole breaker..
