All thermocouple leads have two ends.
One end has the elongated bulb that the pilot light heats up, other end is stubby and threaded, which screws into the gas valve.
Locate valve and pilot, remove bad one, reinstall new one.
This is also the same for all gas waterheaters, ranges, and any appliance that has a steady pilot.
But, sometimes it's the valve. That requires further testing with a meter for 400 to 700 Mili-amp-hrs output or using the magnetic spring loaded solenoid from gutting out an old gas valve.

There will be a number printed on the side of the regulator, contact Procom direct or just put the number into google search and something will come up.

dirty pilot, not enough combustion air, improper gas pressure or a bad gas valve.

Procom QL300TYLA... | Answered on Jan 23, 2011

you will have to check too see if you have gas both sides of the reg first break the line to check , you could have air in pilot line which will take time to come through as the pilot injector is small or the pilot is blocked , down to how you blew it out back in to the heater or out of the gasline .

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

If the pilot is going out as soon as you release the gas knob, you have a bad thermocouple. It is the safety probe copper colored that is screwed into the gas valve and the other end is in the pilot flame. It is a little tricky but you can get it out and replace it with a universal thermocouple sold at good hardware or farm center stores.

Procom QL300TYLA... | Answered on Feb 07, 2010

The most common problem would be the thermocouple is bad. The thermocouple sends a small current from the pillot light to the safety shut off valve. When it goes bad, the valve doesn't receive a signal, so it shuts the valve and keeps the heater from leaking gas into the room. The thermocouple is easy to change. It is the little copper wire you see that runs from the pilot light assembly to the valev housing. It just unscrews. I would take it with you to the parts store, because they come in different lenghts. Hope this helps...

The least bit of dust in the pilot safety mechanism makes it think the oxygen is low and shuts down the heater. An easy fix. You blow out the dust from the safety or flush it with rust buster. I have repair photos HERE

This short film has a great demo HERE

You can't. You need an LP gas valve which costs almost as much as a new unit. Pressures are different and orifices need to be changed, the the pressure needs to be reset. Just buy a new unit and be safe.

Remove it and take it to a good hardware store that sells gas heaters. You can also look up on the net at houseneeds.com and other sites specializing in repair parts.

Procom QL300TYLA... | Answered on Nov 28, 2009

Could be the thermopile or bad gas valve. Lets hope for a bad thermopile (costs much less). Are you able to re-light the pilot and does it stay on without the main burner on?
