I got a reddy heater R50A, a hand me down from my Dad. I don't have a manual. I plug it in and the fan starts but it doesn't ignite. I filled it with new fuel before I started.


Here is a service manual for the heater.

http://www.desaparts.com/service_manuals.html

You first need to check for spark on the unit. If you have spark then make sure you have air pup pressure coming from the air pump / rotor on the back of the motor.

If you have other questions we can try to help.

Thank you.

I have a lp 75-125 reddy heater. when pluged in it no longer sparks to ignite fuel. I have the style were the ignitor is always sparking an arc.


The tranformer that sits under the motor for the igniter could be burnt out. You can use an ohmmeter to check it. I'm assuming yours has a spark plug. Make sure it isn't fouled and has a gap of .050".

Heater will not stay on rm60 reddy heater


When you say the heater is coming on does it actually ignite or is the motor just running until the safety circuit kicks it off? The air pump on you heater should blow at 3.5 to 4 psi which runs up to the nozzle which is a venturi which sucks the fuel out of the tank. The motor will generally run for 20 to 30 seconds trying to ignite. If the flame sensor does not sufficient flame during the time it shuts the motor off. Check these items and let me know what you find.

When heater starts it does not always light, I get a C3 code


the ignitor is faulty, mine also did that and I noticed one night that it was shorting out right from the ignition box. I put in a new ignitor and flame sensor and it's fine now. All ignitors are basically the same you just have to do some creative wireing. reddyparts.com still has most parts for your heater.

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.

Igniter lites up fan kicks on and within 5 sec shuts off


Dustin, The ignitor only glows for 5 seconds, just long enough to ignite the fuel. The heater is shutting down because the photocell does not see the correct flame color.
Since you say "comes on for 5 seconds", I can only assume that there is a flame. You do not specify a lack of flame. I am also assuming that you have had the heater running this heater season and the problem just started.

YOU must find out if the problem is fuel delivery related or electronics related. Start by checking the pump pressure.

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
