Question about Reddy Heaters

1 Answer

Only runs for 15 seconds or so.

This unit sat around for years until it was given to me. I changed the sparkplug type ignitor and fuel, put some additive into the tank incase there was any water I missed, cleaned the injector, air filters, and fuel filter. When it's plugged in it runs for about 15 seconds. So I disconnected the photo sensor and it acts the same way. Does this mean the photo sensor is bad or could it be the breaker?

Spark plug will not unite


If this is one of those liquid fuel heaters, change the nozzle, the filter, and clean the pump strainer. Bleed the air out of the fuel line by opening the small nipple (in the fuel line on the side of the pump) while attempting to start it until the fuel comes out clear and not sudsy, then close the nipple if the appliance had run out of fuel prior to you attempting to start it There's no spark plug in it, but a 10,000 volt ignitor.

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.

Ran out of oil but oil is now filled ignitor comes on and flame lights but you can hear it having a hard time staying lit and after about 5 minutes the unit shuts off


With oil heaters when you run out of fuel you **** all of the nastiness from the bottom of the tank thru your fuel system. First I would change out the filter then using the bleeder valve on the pump crack it loose until you get straight fuel no air, you do this a little at a time do not open wide and let it fly as fuel is under pressure and will soak everything. Just crack it then shut it repeat until you get no air.

The breaker button keeps popping on my heater. 14yrs old. stored indoors. was in use for 1/2 hr then sat for an hour. went to start no fire just noise then pop and smoke. took off top cover got sloppy...


There is a good possibility that the motor is not running at full speed. You should attempt to turn the fan and check for stiffness in rotation. The breaker is sensing a high current draw and is perfroming normally. If you find the motor is stiff use a parifin based lubricant. The "Zoom-Spout" Oiler is the most common oil that we use and can be purchased for around $3.00. There is an internal tube inside the oiler you can pull out / extend that is great for reaching into tight places. Make sure to lubrcate both ends of the motor.

The other thing to check is to see if the ignitor is shorted. Read resistance from the wire to the probe surface. If you read resistance the ignitor is internally shorted.

The owners manual is here:

I doubt that the fuel filter is causing your symptom but... if the ignitor remains on due to a lack of fuel flow it may be tripping the breaker. The ignitor should be on for less than 10 seconds.
Fuel and Air Filters are here:

Lstly the ignitor transformer may have shorted since you said the unit is 14 years old it probably has this transformer installed:

This transformer is no longer available and has been replaced by this rather pricey kit:

That should just about cover it. If you need more assistance just repsond here and I will help you.

70,000 BTU Ready Heater


If...the air pump pressure is right, the ignitor glows, the fuel is hitting the ignitor, then the unit will have combustion......unless.....
  1. there is an air leak on the pressure line
  2. there is a vacuum leak on the fuel line
  3. there is a leak at the nozzle adapter
  4. there is a restriction either in the nozzle or the fuel filter
  5. the nozzle is worn and is spraying fuel rather than fogging fuel

Heater shuts down prematurly


If the heater runs fine for the 15 or so minutes without smoke/odor- do this
  1. check for water droplets on bottom of tank
  2. check for restricted fuel filter
  3. test photocell
  4. test safety control (reset)
You don't state whether this is a spark plug heater *or* Hot Surface Ignitor type. I made the assumption you were inquirung about a Spark Plug Heater. Disregard the list if the heater is an HSI type---- troubleshooting is different.

All Pro 200t Will not ignite


John- the ignitor does not stay on for the duration of the running time. It only stays on for the first 5 seconds. This is long enough for the flame to ignite and perpetuate itself, assuming the fuel delivery system is up-to-par. The photocell monitors the flame color and if the flame becomes off-color then the photocell tells the control board to shut the unit down. Naturally, too rich or too lean affects flame color.

Now, I'm confused by your description "the heater cycles 3 times". Tell me more.

I'm glad to see that you checked the pump pressure. Have you used soapy water to check for air leaks all the way to the nozzle? A leak in the airline, fuel line, or a crack in the nozzle adapter will cause no fuel delivery, or reduced fuel delivery as well as reduced atomization of the fuel - all of which can cause a lack of combustion. A restricted fuel filter will cause starvation.

Eliminate all possibilities of a fuel delivery problem before you start blaming electronics because there is not much way to test the board or the photocell successfully without DESA's diagnostic tool. Unfortunately, replacement of the componants is cheaper than the tool.

Have to replace ignitor on coleman furnace every year


The voltage regulator on the control module is sending the wrong voltage to the ignitor or the ignitor is getting wet from condensation. That ignitor should last many years. Replace the control module.
