If the unit lights Check the photo cell this can be done with an ohm meter and good light. Should have continuity in light.

SOURCE: REDDY HEATER PRO 200 WILL NOT STAY ON WITH TOP COVER ON

The nozzle is either restricted or worn to a point that the cone shaped fuel pattern is no longer producing a FOG, but is now producing a SPRAY and is not producing combustion. By removing the top cover the aerodynamics changes and allows the cone to expand & atomize better.

All bets are off, though, if you haven't checked the pressure on the air pump. Setting the pump pressure is easy but critical, especially if your heater has a glowbar & control board. Instructions are at www.reddyparts.com .

Check your heater over thoroughly for the exact model of your heater. "Pro 200" only designates a style and not all parts interchange from one PRO 200 to the other.

SOURCE: reddy heater will not fire.

Your problem is most likely the lack of pressure from the air pump. Your pressure is extremely low. Pressure on a 100k heater should run 5psi. At 3psi there is not enough fuel and not enough air to atomize whats there. Bump the pressure up. If it won't come up, then you have an air leak. Test w/ soapy water. Keep your fingers clear of the fan!

SOURCE: RM115 Reddy Heater forced air heater problem

I had close to the same problem i drain the tank added new fuel still no diffrence so i removed the filter going to the tank pick up flushed out with brake clean it work fine for half a day . I knew then i was on the right track . I went to the local hardware store and bought a tune up kit that had the filter in it,I replaced the filter going to the tank pick up and it's been working fine even in cold weather. Fuel quality has a big part to play in it's abbility to burn in colder tempicures.

I have an older 30,000 BTU spark plug type kerosene Reddy Heater. My problem is this; The heater will run for an hour or so then shut off. It seems as though it needs to cool down before it will allow me...

Try the link below. You can run down the list of checks and also get parts. You need to repalce the nozzle or clean it yearly. If it's older replace plug too. Check pump pressure.

Wont stay running, fires up then shuts down, has fuel and spark, what else could be the problem. The filters are clean, also


There is a flame sensor inside the case, remove the top half look directly below the nozzle assembly and there it should be. These get dirty so clean it with windex and soft terry cloth rag, there are yearly routines you get in to owning one of these things, and if you do them each year they are good heaters. Biggest enemy is dirt and corrosion be it fuel system or the safety and sensors. The filters both fuel and air are important for proper fuel distribution and mixture.

I have reddy htr 35 was running great,just stopped reset breaker lit right up then went out Pulled cover off fan and spark fine reset it lights right up can see the fuel atomizing flame starts...


Check your fuel lines and most models have a fuel filter in line. A few things come to mind one how old is the fuel? Check the screen in the nozzle assembly by removing nozzle it sits directly behind the nozzle, these corrode and affect fuel flow. While you have this tore down clean the fire-eye with windex and terry cloth rag, it may not be seeing the flame. Check the air filter at the back of the heater as well. These are common problems with these heaters.

I have a Reddy Heater 70,000BTU without a thermostat. It will flare off and within a few seconds the fire goes out and then the it trips out. After a few tries it won't even flare off. What might be wrong?


hello. Your reddy heater is dirty and needs a good cleaning. Also, here are a few other possible reasons why it won't operate properly. Pressure not adjusted to 5.1 psi, dirty outlet filter, clogged inlet filter, bad or dirty photo cell, defective reset switch, pump going bad, dirty injector nozzle, dirty fuel filter, contaminated fuel. Check yours out and do what you can to address each area of concern. Regards, Joe

Heater turns on for a few seconds then goes out


Absolutely K1 or diesel can get old in a hurry, the ultra-low Sulphur diesel has been tinkered with so much that it turns to book varnish much faster than before 2010. Most of those heaters spray fuel past the igniters using a siphon much like a spray paint gun, the suction tube may have dry rot or a small air leak and it it takes but a tiny air leak to kill the siphon effect. Check the tube from the nozzle all the way down to the fuel tank or replace it if you're not certain it is not compromised or dry rotted.

REDDY HEATER PRO 70


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.

Clicks but wont fire


make sure the high voltage lead to the sparkplug isn't touching anything metal on its way to the plug. the clicking may be the high voltage discharging to a metal part, not the plug. those wires age during use.
