I had the problem on my reddy 70 ,30 seconds.and would die.long story short,it was the capacitors.capacitors go bad.took mine off and went down to radio shack and matched them up with new ones.the numbers are on them.solderd them back on and has been running perfect for 2 years. the capacitors are on the chip board for those who dont know.blue and black and look like little pop cans,cant miss them.i hope this helps,should only cost $2.00 to fix.

I have a Reddy Heater R100 that ran just fine until one day it

wouldn't ignite. I took the cover off to see if it was sparking and it

ran just fine with the cover off. I got on the Internet to see if there

was a definitive answer as to why it would only run with the cover off;

there wasn't. So I decided to troubleshoot it step by step instead of

replacing everything at once. You can thank me later.

Step 1: Dumped out old fuel, made sure the tank was completely dry and

clean. Put in fresh kerosene. This is an absolutely hideous job.

Result: Still would only burn with the cover off. Said bad words.

Step 2: Replaced all three filters. Result: Still would only burn with

the cover off. Didn't say bad words, just thought them.

Step 3: Removed the end filter cover and pushed on the pressure relief

ball. It seemed to be stuck.
so I marked the relief screw, counted the exact number of turns to take

it out, and washed the end filter cover and small parts with Dawn

dishwashing detergent. Harsh solvents can melt the plastic on the end

filter cover. Blew everthing dry. Put a little oil on the spring and

ball so they wouldn't rust. Put the relief screw, spring and ball

together, making sure I turned the screw back in the same number of

turns that I took it out with, within a tolerance of about 1/8 turn.

Result: Still would only burn with the cover off.

Step 3: Downloaded a manual from:

http://www.desatech.com/manuals.cgi?products=Construction%20Heaters to

find out the spark plug gap. They didn't have one for an R100 so I used

the one for a R100EDI. I cleaned and set the spark plug gap to .055".

I think later heaters use .075" or .085". Check your manual. Result:

Still would only burn with the cover off.

Step 4: Removed the nozzle. Put a clean paper towel under the input and

sprayed carburetor cleaner into the output end of the nozzle,

backflushing it. Four or five pieces of crud came out, onto the paper

towel. Really cleaned the nozzle good. Blew it off with compressed air

to make sure all of the carburetor cleaner was evaporated. Replaced the

nozzle. Result: O frabjous day! It worked just fine for about a half

hour, then it started coughing and smoking.

Step 5: Removed the nozzle again. Put a clean paper towel under the

input and sprayed carburetor cleaner into the output end of the nozzle,

backflushing it again. Four or five pieces of crud came out, onto the

paper towel, again. Really cleaned the nozzle good, again. Cleaned the

fuel filter and the upper fuel line. Made sure everything evaporated

before I put it back together. Result: works great with the cover on.

Ran the tank of fresh fuel empty. Put the original fuel back in, it

works too.

So, if in the future, I have the problem where it doesn't burn with the

cover on, I'm going to start with the nozzle, upper fuel line and fuel

filter.

Check filter down inside tank. Also you may have large chunks of trash that will not fit into the filter. when heater shuts off it drop the trash and when you start it back up it picks the trash up again causing the symtoms you desribe.

Well this one is trying to detect flame, please try checking the fire eye clean the lens with windex and a terry cloth rag and try to fire it up. Make sure that this eye has an unobstructed view to the flame, not a correct thing to do but jump the eye out and see if you run longer if so replace the fire eye.

Reddy heater has problem staying on


Check the foam filters located in the back, their is also a primary air adjustment slot in the back try adjusting that each time you fire it to see if you can get it to stay on.

Can you see the fuel oil coming out of the nossle? If
not clean it. If it has a cad cell that could be bad or dirty, you might have to bypass it to see if that is the
problem.

Reddy Heater teasing me:)


sound like there is dirt and stuff in the fuel tank.when the heater fires up it pulls this stuff up into the filter.as it runs it plugs the filter off causing the heater to shut off.whe it shuts off the garbage falls back into the tank.when you refire the heater it pulls the garbage back up again.it never pulls it up the same so the time verys every time

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.
