Question about Dayton Electric Heater

Dayton 3ug73 electric heater keeps cycling

This heater is just over a year old. Intially worked great, but now it keeps cycling - heats for 45 secs, then off for 75 secs. Fan works. Same result with the included thermostat or an external thermostat, so I doubt the thermostat is the problem. Is the problem likely to be the high temp cutout?

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 sensor for the thermostat is probably going bad or has bad connections. It is (or thinks it is) heating up fast and therefore shuts of the heater.

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.

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.
