Have you checked the air pressure it should be around 6lbs. to do this is in the back on the filter cover remove plug that is on the left side insert a pressure guage turn on heater and look at guage you can adjust air pressure by turning the slotted screw that is to the right of the guage. If you cant get 6lbs of pressure then check the rotor assy. and check to see if you have any cracks any where on the filter cover.

Try checking the air line and make sure it's tight where it connects to the compressor and the fuel nozzle. Also check the fuel line where it connects to the fuel filter and the fuel nozzle. If the ends are cracked or stretched, make sure you will have enough left to reconnect then and trim some off of the ends so they will fit tight and won't leak air. Let me know if this doesn't help. If it does please take time to vote and leave feedback. nitensheaterservice@earthlink.net

remove the cover and check for spark at plug when plugged in if no spark check spark plug gor proper gap, or defective transformer electronic ignitor if you see spark check for proper pump pressure and restricted fuel flow due to seal leak, filter blocked and restriction in nozzle. I would check for defective photocell first for soot/dirt if dirty wipe with clean damp cloth remove photocell from heater and connect ohmeter on the 1000 ohl (rx1k) scale. Hold the lens up to a light source (60 wtt bulb, with the lens of the photocell pointed towards the source the resistance of the meter should be low by clocking off the light source by putting thumb over opening of cell the resistance on meter should be high, replace photo cell if a change in resistance is not observed during this test, let me know if you need more assistance

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.

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.
