Check that fuel pressure is OK, and also check the air intake is free.
This model should have air filter, in that case replace it.

Here you find also the service and repair manual

I believe you have a pressure issue. The pressure should be 3 to 6 psi. Try adjusting to see if that is the problem.

Heater will not run


You don't say, but I am assuming that the motor is running and there is combustion in the combustion chamber and the heater is running fine, then the reset trips. Is this correct? If so, chances are the Safety Control (reset) is defective. Part number HA3003. The photocell could also be at fault. Check for a dirty lense on the photocell.

But---If there is no combustion in the chamber, then the photocell detects a no-flame condition and then it trips the reset.

Reddy heater model r100a runs approxamitly 15 to 20 minutes then kicks out.fan seems to run fine and already replaced the spark plug.


generally if a heater with a spark plug will run for 10 minutes or longer then that’s an indication that the electronics are functioning properly, so for now, eliminate "any fuel delivery problems" before trouble shooting the electronics. The spark plug should spark for the duration of the run time. If the flame goes out the heater shuts down (just like its designed to do). Imagine the fumes & danger involved if the heater continued to pump raw fuel into a hot combustion chamber!

Some possibilities:
  1. the plastic end cover is cracked. When the room heats up the crack expands allowing the air pressure to fluctuate.
  2. the air pump pressure is not correct. (instructions at www.reddyparts.com )
  3. the fuel filter is restricted.
  4. the nozzle is restricted or worn.
  5. there is an air leak between the pump & the nozzle.
  6. water in the fuel. When a droplet passes through there is a momentary flameout condition which will cause the photocell to shut the unit down.
  7. The photocell is defective

R155A Reddy Heater Help!


This is going to be a tough one. You have been thorough, done it right, and it damn sure ought to fire off every time!

There is something that is causing you a problem and don't think that because you put in new parts that you didn't get a bad part. It happens. Not often, but it does happen. I have rec'd nozzles from the factory that had the orifice installed sideways, so, I know it happens.

If the ignitor glows- (it only stays on for 5 seconds, then quits)
If the fuel fogs (not sprays)
If the fuel hits the glowing ignitor
Then it should fire off-- every time.

Now, if the photocell doesn't like what it sees, then the photocell will shut the heater down within 5 seconds, but it at least should have ignited. Right? Unless the photocell or the board are bad. Maybe.

Lift the top, and watch. What's happening. Are you having a fuel problem or an electronics problem? For instance- is the ignitor glowing every time at start up or only sometimes.

Let me know what you find.

1 Answer

Ignition


This is a "probably". The reset button trips because the photocell fails to see a flame in the combustion chamber. That's its job.
Check the ignition device ( transformer, coil). See if 110v going in. If there is no spark coming out, replace it.

Trys to start. Motor turns slowly (revolution in 2-3 seconds).


Either:
  1. the reset (safety control) is bad
  2. the photocell is defective
  3. both of the above

Wont fire


No solution. The electronic control monitors the flame in the heater using a photocell. The ligth intensity and frequency are monitored to insure that the heater getting a good burn and therefore not emitting a high level of toxic gasses.

Causes:
dirty photocell
bad fuel causing bad flame
