Take air preassure from a compressor and turn the fan blades in the back of the motor while you reset the switch. the you know its gumming up and needs to be cleanned and changed parts or a kit added from your local lawnmower supply house.

Runs than shuts off after a few seconds


Is this a propane or kerosene heater? If it is kerosene, check your fuel, clean your tank and start with fresh fuel. Check your fuel filter/air filters at the back of air pump. Make sure your ignition system is working.

Reddy Heater R55 55,000 BTU heater spits and sputters but CONTINUES TO RUN. Air pressure is at 3.4 (was 4.0). new lines, Plug is firing well, fuel is old but clean. My question is: is there supposed to be...


If you brought the heater to my shop with the great (no lie!) description of the problem we would immediately grab a flashlight, shine into the tank and look for water droplets rolling on the bottom of the than. (Keep in mind that a layer of water can be on bottom & not show up with the light)

The next thing would be to use soapy water and try to find a crack in or around the plastic cover and move all the way to the nozzle looking for an air leak. 3.4 at the gauge doesn't mean the air is going all the way to the nozzle.

Next, remove the top cover. Does the heater run fine once removed? If so, replace the worn out nozzle. That heater has some age on it and DESA recommended annual replacement.

The filter is more of a strainer than a filter. It is hollow.

I have a portable forced air heater Model R55A heater size 55,000/Hr can I use diesel fuel instead of kerosene?


You can, but prolonged use of diesel fuel will burn out the cone faster. Too hot. And it stinks alot worse than kerosene.

Reddy Heater R55 concerns


They are grounds, and should have two screws on the burner tray to hold it from moving. On my heater this is where the grounds get attached. It gives the igniter a dedicated direct ground.

Kerosene Reddy Heater, fan comes on, but it won't ignite, it just blows kerosene out the front. There is no electricity getting to the plug. Please reply soon, I need it tomorrow!! Thanks


Your description does not leave much to go on, because you don’t state the model heater that you have. You see, there are 2 different technologies that come into play on portable kerosene heaters. First there is the older version spark plug type heater, and, second there is the newer computerized type with Hot Surface Ignitor (HSI) technology.

Since you state "There is no electricity getting to the plug", the KEYWORD here is PLUG. I am going to assume that you have a spark plug type heater. NOTICE: if your heater has HSI technology- disregard this post because it will not apply.

Causes for "no electricity to the plug":

  1. no electricity to the unit
  2. a defective Safety Control (reset)
  3. a defective photocell
  4. a defective Ignition Control (transformer)
  5. loss of ground to the Ignition Control

I am including a link to some troubleshooting tips for spark plug type heaters. These heaters are relatively simple, but, be careful. Stay away from the fan and take precautions from the obvious shock hazards. Troubleshoot each of the above until you find the problem.

Good luck!
