Try a part from a similar heater like Mr. Heater Most of the parts are identical they just mount a little different, put the new part on your old mount. Had a similar problem with my dyna glo and with a little rigging it works like new.

I have a 35,000 btu Reddy heater that won't fire at the spark plug but is getting a signal from the magneto. Is the magneto bad or does the spark plug have to be in the mist of kerosene to spark?


  1. The FIRST STEP in diagnosing any heater problem should be checking the output of the air pump. Determine the air pressure required for the heater model that is being tuned. The air pump, in turn, is responsible for fuel delivery.
  2. If you do not know the required pressure look for a decal on the side (usually) of your heater. This decal will state the model number, serial number, fuel capacity, pump pressure, etc.
  3. If your plastic end cover looks like this......
m29609t.jpgM29609 has 2 threaded holes. The hole on the left has a square plug inserted. Remove the plug. Screw in the nipple end of the gauge into the threaded hole. Check for air leaks with soapy water.
or
If your plastic end cover looks like this......
m16545t.jpgM16545 has 2 threaded holes. The shorter projection with a hole on the left has a square plug inserted. Remove the plug. Screw in the nipple end of the gauge into the threaded hole. Check for air leaks with soapy water.
4. The other hole (longer projection) has a screw with a hole which adjusts a ball and spring relief valve assembly. Carefully adjust the screw until the gauge is reading the pressure level that is specified on the heater's label. If operating properly, the pump should produce more pressure than is required to operate the heater. The relief valve allows the excess air to escape before being sent to the nozzle.
5. Replace plug. Test for leak.
6. If you are unable to reach the desired pressure spray soapy water around the seal of the end cover- at the same time check the plastic cover for a crack. A cracked end cover will not allow the heater to perform properly and will not allow for an accurate reading. The pump must be set at the specified pressure in order to have adequate fuel delivery an adequate fuel atomization. Replace if needed.
7. If you set the pressure to specs and the heater does not perform properly or the cone does not glow a soft red, then check for other fuel delivery problems such as a clogged fuel filter, cracked rubber hose, clogged or worn nozzle, or a cracked nozzle adapter. Soapy water lightly sprayed in these areas will quickly identify the problem most of the time. Any air leak will create problems.

Replaced rotor on my 115 ready heater now it puts out way to many fumes,it burns my eys.any suggestions


The fuel/air mixture is not right.
  • Start by setting the pump pressure to factory specs.
  • Stop all air/vacuum leaks between the air pump & nozzle
  • If the problem persists, replace the nozzle. Desa recommended annual replacement. Simply stated- the nozzle wears out to a point that the fuel is a spray rather than a fog and the fuel can't burn completely.
  • You don't state the type being burned. Diesel smells more than kerosene.

Replaced ignitor No Fire


Make sure that the ignitor is in the mist of atomized fuel. Or better yet do you have signs of fuel atomization? Check fuel filter usually an in line transparent type filter, if it is clear check the nozzle they have a screen inside as a filter as well no fuel there lines to the tank are next in line if you have fuel up to the nozzle it may be time to replace the nozzle sorry but you can not clean them any slight bend or widening of the holes changes the rate of the nozzle. Pay attention to the GPH rating and spray angle when replacing the nozzle.

After sitting all summer now goes in to a flame out condidtion after a few moments of operation


Make sure the filters in the back are clean and make sure the fuel line
from the tank to the nozzle are tight. You might also check to make
sure nozzle is clean. Make sure fan is operational. If it has spark ignition make sure that is cleaned up as well
