No spark i have an ancient 50K btu heater that wont spark. we get fuel and the fan does run but no spark i think we might need an electronic ignitor. Is this part available or is there something else we should be looking at?

If its as ancient as you say it probably has an ignition transformer,open up the unit and isolate the transformer and check primary/secondary transformer windings for continuity,if so then either the electrodes or spark plug thats on the secondary transformer could be defective,be careful POWER OFF secondary can have up to 4,000v.a.c. when plugged in

Wont fire after following start instructions


OK-- Let's go thru your trouble shooting steps, and what you found:

1.) Fuel: Sufficient, and right type?

2.) Has the unit fired and run before?-- What is different in sounds, or settings now?

3.) How does this unit ignite the fuel?-- With Spark, or with Glowing ignitor?
If Spark-- can you hear it sparking?

If Glowing ignitor, -- can you see the glowing? (in a darkened room..)

4.) Can you see that Kerosene is spraying at the nozzle?-- is the pattern correct?

5.) Have you check fuel and air pressure settings-- according to the manual?

After observing these details-- let us know what other clues you are observing now.

I'll be here to take you to the next step, if you like--- Just add your new comments in the 'respond' box-- they will send them to me for further follow-up.

The heater fan runs for about 5 seconds , does not heat and than turns off.


This could be several problems. Check your fuel first. If it is old fuel from last year, get rid of it and fill with fresh. If it has water in the tank, your spraying water to your ignition source. If you have fresh fuel, it could be a fuel filter stopped up or your air pump is not set properly. Also check your ignitor to see if it is working properly. Some have a spark plug and some have a glow type ignitor.

I left Diesel in my heater all year long i ran it this winter and it stopped how do i fix it


Leaving fuel in heater shouldn't create problems. Check reset, if so equipped to see if there is power, Check ignitor to see if it is firing. Check fuel filter and nozzle screen to see if they are plugged. If you have good fuel spray, good spark at ignitor,and the electric eye can see flame, it should run. If there isn't any spark at the ignitor, the high voltage trandformer could have failed.

Wat the hell is wrong with my dayton heater?170,000 btu oil fired...wont stay runnin?on shut down puffs like a mutha....


Most use a spark plug to ignite fuel it could need cleaning. You also could have water in fuel or dirt
check and clean ignitor/spark plug clean fuel line and nozzle, drain and clean tank Check for water in fuel by tilting unit to have a low corner siphon fuel from that corner after 1 hr inspect for water.

Reddy Heater will not ignite flame


Please answer the following questions. There are several folks on the board that can help but we need to know some vital information so we can get started. Answer these, if you can:
  1. Which Pro 110 do you have. We need the exact model number. Pro 110 is a series of heaters.
  2. Does the heater have a spark plug or a glowbar (HSI)?
  3. When the motor runs is it pumping fuel?
  4. When the motor runs is the spark plug firing (or glowbar glowing)?

www dot desatech dot com is a parts distributor for reddy heat products. on their main page they have a short troubleshooting guide. the motor needs to provide 3.5 psi of air across the fuel nozzle to suck the fuel out of the reservoir. check your ignition source (spark plug, hot surface igniter) if the hot surface igniter is broken get a new one, if the spark plug don't spark, check the gap might be too big. see if the spark plug is grounded. poor grounds will cause intermittent sparking. check the high voltage wire for breaks in the insulation, might be shorting out to ground BEFORE the plug. gap should be 75 thousandths.
