Kerosene forced-air heater won't start

I own a forced- air kerosene heater that won't ignite.
It has plenty of fuel in the tank and the power switch illuminates when i turn it on. There is a fuse on the inside of the right panel that check out "ok".
Is it common for the igniters to go bad? If so, how do I check it?


Thanks for "ANY" help
Rick

Rick---A couple of things to check. With the unit off and unplugged, remove the spark plug-(Note-there may be a little setscrew which you have to remove first)----Put the plug wire back on the plug and ground it against the side of the heator and start it just briefly to see if the plug fires----If it does, then again with the unit shut off, remove the nozzle which has a set screw holding it in. The nozzle has 2 rubber lines running to it and leave them on and then start the unit (Note, be aware that in this test and the plug test that when its plugged in, the fan runs, so keep the plug wire and the rubber lines away from the fan) With the nozzle removed, watch very closely to see if a mist comes out of the nozzle after you plug it in. If no mist comes out, then you probably have either an air or fuel problem.---With the spark plug test, if there is no spark at the plug, the easiest way is to install a new plug and if there is still no spark, then the ignitor is probably bad----------On the nozzle test, try taking off the 2 lines on the nozzle, one line goes to the fuel tank and the other line is the air line (take note which line goes where) first blow thru each connection on the nozzle to see if its plugged and if its not then blow thru the hose going to the tank and you should hear a bubbling noise in the tank--if not then, its plugged or the hose is split----------The other line is the air line and if you can't get anything on it, the filter may be very dirty----behind the filter, there should be a port for checking the air pressure when the unit is running----The unit I have runs on 3 psi pressure, BUT yours may run on a different setting--That psi setting may be stamped on the unit behind the filter---Hope this helps

Remove the top of the heater - move the fan & motor backwards and remove the ignitor - if the element is fizzled go to www dot desatech dot com. you can get new hot surface ignitors from here. they also have spark ignition systems if yours has this.

Runs than shuts off after a few seconds


Is this a propane or kerosene heater? If it is kerosene, check your fuel, clean your tank and start with fresh fuel. Check your fuel filter/air filters at the back of air pump. Make sure your ignition system is working.

I have same heater and problem-1) Check fuel inlet screens at bottom of hose in tank 2) Check air filters at fan module opposite end of the fan blade 3)Check for spark in ignition chamber 4) Check for fuel flow in ignition chamber (look at pressure gauge at opposite end from air exit) You'll have to remove the top cover to do these checks. The side covers will hang on each side ok. I hope these checks help you out.Good luck.

Heater used once 3 yrs ago. Now wont start.


When the heater hums is the fan turning. If it is I would add more Kerosene. There is no shut off but the Kerosene is sucked out a tube from the top of the tank. This tube does not reach quite all the way to the bottom of the tank. Your heater should hold about 9 gallons if it is empty. A couple of gallons would give it plenty to run though. Let me know.

All Pro K75 will not ignite. Spark igniter does


most kerosene heaters are basically the same - reddy heat, dynaglow, desatech are all the same. there's a small air compressor built into the axially mounted fan that points forward. the air pressure needed for fuel is 3-5 psi not less, not more! the air feeds through a side inlet to the fuel nozzle where it creates a vacuum venturi to **** fuel from the tank and propels it through a fan nozzle. the aerrated fuel hits the hot surface or spark and ignites. as long as there is heat and air the heater should function.

HARD START AND BLOWING SMOKE


clean all of your filters and the spark plug and go back to useing K1 kerosene. Diesel fuel has a higher ignition temp. burns dirty and has a tendency to gel.

Garage Heater


the kerosine heater uses a spark plug for ignition and a photocell to detect flame. at the back end of the blower motor is an air compressor. it is a vane and diaphragm compressor that supposed to put out 3.6 psi of air to the fuel nozzle. the fuel nozzle is a venturi type that creates a vacuum across the orifice to suck fuel from the tank. try this site for spare parts www dot desatech dot com. its the same place I get parts for repairing heaters.
