Question about Procom ML300HGA Heater

2 Answers

Pilot Lught I'm having problems keeping the pilot light going on initial start up. The pilot lights fine but it doesn't make any difference where the control knob is, it (the pilot) will not stay lit. I've tried "fudging" a little each way on the setting, still no luck - the pilot simply won't stay lit when I release it after initial warm up of the pilot. Has anyone else had this problem and what was your corrective action??

The theropile is connected to tha safty valve .the switch inside is magnetic and can stick. Light pilot and try tapping on it with handle of a screwdriver. Otherwise the valve can be replaced .

When you light the pilot you hold down the knob for the coupler to get hot at this time don't let go of the knob turn it to on position as quickly as you can. If that doesn't fix it you need to replace the thermal coupler. try that

I have a Williams model # 2509612 wall heater. I replaced the thermocouple, cleaned the pilot light gas line, but the pilot light keeps going out after cycling. Any suggestions?

Remove your pilot assembly and remove the aluminum gas line going to it. Be careful when you take this off because there is an orifice inside of it that may or may not fall out. If it don`t fall out remove it. In the top of are a couple really small holes. Make sure they are clean. Also again clean the pilot hood of all debris. Reassemble everything and it should work fine. If not buy a replacement pilot assembly because I have had some that i couldn`t get clean enough not matter what I tried. Doesn`t happen often but does happen. New assembly always fixes it but a good cleaning usually does it.

I have a PROCOM model ML300TBA, two years old. Here is my problem: Pilot lights fine. Burner lights fine. When I go back the next morning, often times it is out. Burner and pilot are out. It will...

You could try cleaning up the thermocouple with steel wool. Some manufacturers call this a flame generator as well. Any how make sure it is clean and positioned in the top center of the pilot light for best signal. This is only speculation as these are common problems that will arise on heaters in general. This also turns the gas to the burners and pilot light so thats why to start here first. Hope this helps you out.

Williams debonair wall heater + pilot light problems

THE flame from the pilot should shoot past the thermo-couple and heat this up and make a small amount of mili- amps to prove the pilot light is lit. ..So if the flame doesn,t go past the thermo-couple it won, make mili-amps or its tme to change out the thermo-couple, They only cost lest than $8:00 and you can change it!

My pilot light keeps going out on my comfort glow infrared propane heater what could be making it go out?

The thermocoupler is faulty. It is that bulb that sits i the pilot flame. It controls the gas valve so you won't get any gas if the pilot goes out.. So, the thermocoupler needs to be replaced. Inexpensive and easy fix. Good Luck _Ned_

Pilot light keep going out will sometime stay on 3 hours then go

Great, if you are not skilled in working on this type of appliance the best thing you can do is to call a professional out. Be careful in picking a service company, there are a lot of dishonest people out there. Try to get a reference from somebody in the construction trade that you trust.

Unable To Keep Pilot Light Lit!

I have a Williams top vent gravity wall furnace (model 5009622) and I had the same problem. I had to take the cover off the furnace -- screw on top and two at the bottom (open the access door and there is one screw on each side) to get to the reset button for the vent safety shutoff system. On my furnace it's on the left side toward the top of the unit. I pressed the little red reset button and it's been working ever since. If your furnace is properly installed and doesn't have bird's nest in the chimney, it should work fine. Good luck!
