Procom propane heater will light the pilot but not the burner

My procom propane heater will light the pilot light but when I turn the knob to turn it on I hear a short hiss, but it doesn't light and the pilot light gets really small. If I do this a few times I get a flash of flame then nothing. I have taken the front off and vacuumed everything out like the manual says, but no change in behavior. The propane tank is full and on, but I don't know how to test the pressure at the heater.

The pilot and clean the injector and see if this is clear then try it , you will need a pressure gauge to check the gas pressure ,

Why does burners and pilot forced off after burners are engaged


We get asked this question many times.

If you light your pilot light, hold in the button and then when you release it and the pilot light goes out, generally you need a new thermocouple. Gas repairs can only be undertaken by a qualified gas technician so you can't do this job yourself.

The thermocouple is a safety device that recognises that the pilot has a good flame and is enough to ignite the main burners. The thermocouple open that valve to the burner.

In limited circumstances the thermocouple doesn't need replacing, either the shield that aims the flame to the thermocouple has become dislodged, or the pilot jet is a little blocked by debris. Either way, having the appliance serviced by a qualified gas fitter is the way to go. I am sure you will have seen news stories about explosions caused by gas leaks and faulty appliances.

Pilot light wont light will spark, but no propane


verify the inlet pressure to the heater. those pezioelectric spark lighters are garbage. make sure all manual shut off valves to the heater are open. Pilot tubing may also be blocked

Burner won't light, pilot is burning just fine.


Once you get the pilot to light and stay lit did yall move the burner knob to the ON position? Is the temp knob all the way up?

Kozy world propane wall heater pilot will not light


This can be caused by several things:

1. The inline gas valve running to the the heater is OFF. Turn the valve ON.

2. The gas control knob on the heater is not exactly in the PILOT position. Unless the knob bottoms
out and you feel strong pressure (other than spring pressure) pushing back at you. It's not exactly
in the PILOT Position. Once the pilot lights, hold the control knob in for 30 seconds to 60 seconds
to allow the Thermocouple to full heat.

3. The pilot is dirty and needs to be cleaned, as do the burners.*

4. The LP Gas Tank is empty or to low to maintain te proper gas pressure.

* Here is a link to a demonstration on how to properly clean the pilot & burners.

The pilot on my Procom QL300TYLA will not light. It appears that no propane is getting to the pilot. I tried lighting the pilot and burner with a BBQ lighter but nothing. No propane getting to the unit....


sounds like you have a blocked pilot injector. normally part of the pilot head. if you can remove it , blow it out with compressed air but it must be removed from the pilot head. commonly known as a Pilot restrictor,Pilot spud or Pilot injector

My propane heater not working right


This could be due to insufficient gas pressure. When you turn the knob to get the flames going, observe the pilot light. If it gets smaller, or burns with less intensity, it means you have insufficient gas pressure. If the pilot light gets smaller, the temperature of the thermocouple drops, so the electrical current produced by the thermocouple also drops. The stove interprets this drop in voltage to mean that the oxygen level in the room has dropped (because a drop in oxygen content likewise would cause the pilot light to get smaller).

When control knob in"pilot" position, burners light, but pilot light and burners go out when released. Burners will not stay lit in any control knob position .


It has a thermo-couple that lets the gas valve know that the pilot light is on. If it does not get the heat signal to the valve, it will not turn on the gas. The end of the thermo-couple has to be in the flame of the pilot, and tight on the other end, and must be tight on the other end.

Pilot goes out!!


My manual shows three possibilities:  1) Insufficient fresh air available for combustion, so ODS kicks off gas flow 2) Low gas line pressure (should be between 11 and 14") or 3) ODS/Pilot is partially clogged.  Toll free number for ProCom is 877-886-5989.
