SOURCE: Dayton 3EV51 torpedo heater

Dayton heaters at one time were manufactured by DESA or a predecessor and labeled DAYTON for Grainger. I have been unable to find any specific reference material to "Dayton 3EV51".

There were 2 types of motors used. I suspect your heater has a starter relay. The solid state relay was used to allow the energizing of the start winding which would allow the motor to achieve approx 80% of rated speed, then the relay would de-energize the start winding to prevent overheating. The relay is not attached to the motor, except for the wiring.

5ef4624.jpgThis is what the starter relay looks like. If yours has one check to see if it is energizing the starter windings at start-up. If not it is probably defective. The part is still available at www.reddyparts.com, I think, but today's replacement part looks slightly different.

If your motor does not have the relay, then the motor has an internal start-up system which is not serviceable, but the motor is probably still available. Most of the time the motor's part number is printed on the label.

Good luck!

These are only 1500 watt heaters.

They 'could' heat a 20 x 20 foot room (with good, tight construction), with a slow temperture rise.

SOURCE: My honeywell gas suspended garage heater will not

The pilot light has to be lit before gas valve will operate. That's a safety feature so the valve won't open and fill the garage with gas and possibly cause an explosion or fire. If you have a standing pilot and can't get pilot to stay lit, it's usually the thermocouple and it will need to be replaced. Once the pilot is lit, the gas valve comes on and heats the combustion chamber up to approx. 100° to 125° a thermostat controlled fan switch will close and bring the blower on.

SOURCE: lakewood heater 792 will not work

The bottom switch is bad. Unplug bottom wires and touch them together, if heat and fan comes on your switch is bad.

Check the blower motor capicator. It should be mounted close to the motor with 2 wires to it (brown,brown/white).
Turn the blower on the thermostat and spin the squirrel cage by hand and see if it runs after by itself. If it does then definitely the capicator is bad .If it still doesn't run then check to see if there is voltage going to motor.
If thermostat is calling for fan and there is voltage present at the motor terminal then the motor is bad

I would first remove the fuse for the heater control head for one minute and then put in and retry.
The control head could have locked up on you with a volt spike. The rear defrost switch does not go through the same circuit in the heat as the hvac controls. Could be a broken know also.
Could also be mechanical linkage on side of heater box above accelerator pedal may have broken or popped apart. or if electrical motor control may be actuator.

Fan runs for awhile, shuts off by itself, then comes back on. This problem keeps reaccuring.


that normally means that the fan motor is getting hot .. there is a thermal protective switch on some fans and on all heater/fans ... some protective switch designs allow the switch to reset when the motor has cooled. that allows the fan to come back on but if the problem is not resolved then it just gets too hot again .. in the case of a space heater then low or blocked air flow will overheat the heating elements .. that will likewise trip the thermal switch .. if you have just a fan (not a heater/fan) then chances are the motor needs oil in its bearings .. check to see if it spins freely .. if not than lub with a good light weight oil like sewing machine oil .. dont use oil containing teflon or other such additives .. that is only for bigger motors and will cause very slow start up in small motors .. make sure there is no dust stopping air flow thru the motor ..you can blow that out with canned air from any hardware ..

You have a heat problem caused by dust blocking the vent and fan or your fan is faulty and not spinning freely.
Remove the dust from the fan and heatsink, check to see if the fan spins freely. If the fans is faulty, replace the fan.

My Dayton garage heater model 2E636B does not heat up.


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.
