Question about Reddy Heater RLP100 Portable Forced Air Propane Heater with Variable Heat Ouput

2 Answers

DESA ReddyHeater R55BT will not stay lit. Sometimes it will huff and puff and blow a cloud of black smoke and quit; other times it will light for a moment or two and go out; others still it will run 2-3 minutes and quit. I took it to the shop for this same problem 3 yrs ago and it worked OK but not like new. Did they clean a flame or oxygen sensor that now needs replacing?

    Ok, I knew about the photo cell but not the cracking problem. I'm going out to the garage right now and check this idea; it's the best I've heard yet. Sounds like I might need a new cover for the air pump filter. I'll let you know if this fixes the problem. Thanks.

This unit has neither flame sensor or oxygen sensor.it has an photo cell in it.look at the plate that is on the back of unit.that is the air pump filter cover.if you look very closly you will probbaly see tiny cracks around one of the holes,either the adjuster or the plug.these covers crack all the time and they are not noticeable.when they crack it changes the air pressure and the unit doesn't work right.let me know and i hope this was helpful to you.

There are four possible answers to this problem, if the heater starts normally, runs for a few seconds or minutes and the shuts down but was still running normally at the time of shut down, this could be caused by the photocell, also known as the flame out control. This safety device may be failing, shutting down even though the heater is working normally, check the operation of the photocell. The second cause may be partial fuel filter blockage, the heater is effectively starving itself of fuel, so the flame blows out, hence the puff of smoke, and then shuts down on the safety cut out. Third cause, if this model has a compressor at the rear of the motor, the problem could be low pump pressure, caused by wear or contamination of the carbon blades, this would cause the wrong amount of fuel to be syphoned up, with weak fuel mix the heater may blow itself out and shut down. The fourth cause, perhaps indicated by the puff of white smoke, is contamination of the fuel with water, water will cause the white smoke and also is indecated by white residues or a power like substance on the end plate of the heater which glows red hot when burning.

GWN10T pilot blows itself out


You must clean the pilot regularly to ensure it burns properly. Use a small can of air for cleaning computers and blow air through the pilot to remove dust and small particles that accumulate in the pilot barrel. Use several burst being that it is 2 years old and has not been blown out. THe manual references cleaning the pilot in the maintenance section.

Heater will not light


I had similar problems with a older Reddy Heater. I bought a 0-15 lb. gauge and removed a plug on the control end of the heater. Turn on or plug it in and set the fuel line pressure as listed on the data sheet (also listed on the heater).

IMPORTANT. This type of heater will not light if the oxygen level is below safe limits. You need more that 14% to support life. Normal is 21%.

Check plug gap and depth of the tip. The spark may be to far into the fuel spray flooding it out. DESA says use a standard spark plug washer or two for shims if needed.
