need to check you fan wires, some have differant colors on the moter for the differant speeds, you may need to change the fan speed by unplugging one of the wires and replacing it with another. hopefully you still have the manuel , check with it first!!!

Sounds like it has a bad fan switch wich is no more than a small circular bi-metal switch that expands when heated closing a switch. Get a parts breakdown off the net. I am sure you could find the switch in your area and replace it yourself.

SOURCE: Dayton 3VE59 Gas Utility/Portable Heater won't

Just repaired one of these, problem was that main gas valve was not opening, valve is controlled by a vacuum switch, vacuum is created as fan blows air down tube past bent up metal flap near front bottom of heater (slight low pressure zone created). If vacuum switch is miss adjusted it will not close when fan is running and no gas flows. this is easy to check as vacuum switch also has a pressure port on it. With gas disconnected, remove bottom cover, locate vacuum switch (it has a hose clear plastic hose connected to it, in opposite corner is another hose connection, attach a length of hose to it that you can blow lightly into. With heater plugged in and no gas connected (USE CAUTION OF WIRE!!!), turn heater on you should hear after a few seconds the ignition and then a loud click as the gas valve opens, if no click blow lightly into end of your added tube, if you now hear a click the gas valve just opened. if you stop blowing you might hear the gas valve click again as it re-closes. If this is the case the vacuum switch needs to be adjusted slightly. THIS switch is hear for your safety, Adjust at your own risk!!! This can be done with a screw drive in the top, rotate screw slightly while checking if the fan alone causes enough vacuum to make the switch work. DO NOT over adjust. check safety operation before hooking up gas by placing a piece of cardboard or wood over the air intake and the exhaust to block airflow, if the air flow is blocked you should hear the gas valve drop out and reconnect as air flow is reestablished. Hope this helps

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.
