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.

Dayton 3EV51 torpedo heater - 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!

Hello i have a international harvester model 100 diesel portable torpedo haeter. my problem is that when i plug it in i get a humming noise and it doesnt start. can u please help????


Sounds like the fan/fuel pump motor is not turning so try this. Take the top section of the heater tube off, this exposes all of the internal working parts. Now locate the fan motor and fan, try turning the fan by hand, should spin nice and easy if not take a light oil or I like PB Buster and oil bearings on the shaft behind the fan, then first set in the front of the motor, then the bearings at the rear of the motor. You do this and spin the fan by hand as many times as it takes for that fan to spin freely. Then plug it in and try to fire it off, if it worked shut it off put it back together and happy heating. If not you may need a new fan motor or could be something in your fuel pump, usually it will be motor related .

Have a 120000 btu fuel fired torpedo heater that fan spins and fuel drips but no spark


fuel is atomized by the blower fan, and a sparkplug provides the ignition source. this sparkplug provides constant ignition spark for the process.

Dayton Model 1VNX5 Kerosene clicks like crazy but won't light


I have the same heater with the same problem. I took the top cover off, removed the ignitor and bent the probes slightly closer. Use two needle nose to prevent breakage of the holder. It has been working fine since.
