SOURCE: no hot water, pilot light lights but no burner ignition

Thermo coupler may be defective. it controls the main gas valve by closing main if pilot is out. make sure thermo coupler bulb is positioned over and near tip of pilot flame, but not in the flame. Thermo couplers are inexpensive and easy to change out.

SOURCE: Propane patio heater ignition problem

I would change the thermocouple and here is why:

The thermocouple is the pilot's, well, co-pilot! It is the electronic device that senses if the pilot flame is hot enough to sustain burning the gas fuel from the burner. If the thermocouple thinks it's safe, then it keeps open the main gas valve located in the pilot assembly. If the thermocouple does not sense enough heat from the pilot flame (such as when the pilot is out), then the thermocouple shuts off the gas valve to the burners.
How the Thermocouple Works
So what is this thing and how does it work? Well the thermocouple (technically called a thermocouple junction) is a device that contains two metal wires welded at the ends and placed inside a protective metal case. The thermocouple sensor is found at the business end of the pilot flame and is designed to be placed in the hottest part of the flame. The other end is connected to the pilot valve body. As the thermocouple heats up, it produces a small amount of electricity and when it gets hot enough from the pilot, send a signal to open the gas valve by using a solenoid operated by a 24 volt transformer. The thermocouple calls the shots, and by converting heat to an electrical signal, it allows the gas valve to open or close. Once the gas valve is open, gas is then constantly supplied to the pilot and as required for the gas burners (as called for by the thermostat). If the pilot goes out, then the thermocouple gets cold and produces no electric signal to open the gas valve's solenoid and the gas valve shuts off the gas supply to the pilot and burners

Slant fin boiler galaxy natural gas, pump starts and runs. Igniter comes on . Pilot lights. Burner lights. Runs for seconds. Burn shuts down. Igniter starts pilot light, pilot goes out and on and on


The flame sensor, which is located in front of one of the burner flames is probably oxidized and needs cleaning or replacement. If the unit can't "sense" the flame, it will continue to cycle.

Got a brand new3 Procom MD300TBA and when lighting the pilot the whole burner ignites. Something wrong with gas valve. No control from low to high. Either off or full on. Any ideas?


Well, if you have it calling for heat it will light as soon as you turn the knob to the on position.
if that is not the case then I would agree that you have a bad gas valve. Its rare but it can happen.

My furnace wont come on its an automatic pilot so i dont know what the problem is we have enough propane


Hello, Most newer gas furnaces (propane or natural gas) has one of several different types of igniters. The most common one is called a hot surface igniter. This is a ceramic easy to break, glow coil, glowing igniter. Some has a Spark igniter that lights all the burners from a constant spark and some light the burners off a pilot proven /spark igniter. This one sparks then lights a pilot then the burners will come on. In any case if any of these types are not working they could be cracked or broke. Also the inducer draft motor has to be running, the little motor that hooks to the exhaust of the furnace ( if it has one ). This causes the pressure switch to close then the igniter should come on. My suggestion is to call a qualified service tech from your area to assist you. To determine which one of these may be your problem they will have to perform several test. Hope you get going soon. I hope this helped. J

I have a dyna-glo model rmc-40lpt, the pilot light is hard to light up, most of the timr I must use a match to light it....after its lit , the burner bar will fire up just fine , high or low but the flame...


are you saying it lights back to the orfice ?? if so i would say the pilot needs cleaning out a long with the burner which could be blocked with dirt or fluff and at the airports to the burner , and the ignition could need cleaning ,

What is pilot light?


A pilot light is the Flame that runs constantly, when any Gas appliance is operated, it is there always burning, very small flame, that is used to "Ignite" the main burners in the device.

I replaced what I thought was a bad igniter.But still had no glow from new igniter. Must be something else.Where do I go from here?


Hello there: The oven bake burner and ignition components are located beneath the oven cavity. In most cases the oven bottom panel can be removed for access (check your owner's manual) but on some models the oven burner has to be accessed from below in the warming or broiler drawer area. If accessing from the top, a 'flame spreader' (flat metal plate) above the burner may also need to be removed to see the burner itself.Many ovens use a single oven burner in which case they only have a single gas valve and ignitor. The same burner is used for both bake and broil functions, the broil usually being in the drawer area below the oven. Higher-end models may have a separate bake and broil burner. On such a system there will be two ignitors, one for each burner. They may also employ a 'dual' gas valve (see illustration above) instead of using a separate valve for each burner.Some range models may have an additional broil burner located at the top of the oven cavity which may be referred to as a 'waist high' broil. If not, broiling usually takes place in the drawer area below the oven, which uses the same bake burner for the broil function. Most gas ranges currently available employ one of 3 basic gas ignition systems; pilot ignition, hot surface ignition system (which uses a 'glow bar' or 'glow coil' - aka an "ignitor") and a spark ignition system. The latter two being referred to as "electronic ignition" systems as they use electricity in one form or another to operate the oven heating system. Only the pilot ignition system has an actual "pilot" (which is a small but real "flame") which might need manual lighting.
If the surface burners of a range are a spark ignition type, the oven IS one of the possible kinds of electronic ignition systems and thus will not usually have a "pilot" which needs lighting. Be aware though that just because the surface burners might light via a spark doesn't necessarily mean the oven uses the spark type ignition system too.
There is one older style of electronic ignition system which does also use an oven pilot but it is very rare and such a system hasn't been used in oven models since the early to mid 70's. It is the 'constant pilot' *electronic ignition* system.


Making Observations
The oven burner's operation will usually need to be directly observed while in operation as the first step to troubleshooting problems.Ignition System Type Links
Ignition System Types:
  • Pilot Ignition
  • Electronic Ignition with Constant Pilot (rare)
  • Electronic Ignition with Glow Ignitor (most common)
  • Spark Ignition System

  • Is there continuity between the oven gas valve's terminals?


    Hot Surface ('Glow Bar') Ignition System (most common)
    This is the most popular system currently used for ovens and is comprised of a control mechanism (whether thermostat or electronic control), the oven ignitor and an oven gas valve.


    What happens in this style ignition system is that the thermostat or electronic control switches power to the oven ignitor and gas valve circuit which are connected in series (one after the other). As power flows through the ignitor it heats and draws current (measured in amperage). Once the oven ignitor draws a specific amount of current the oven valve opens to allow gas to flow to the oven burner where the glowing hot ignitor (glow bar) ignites it. Power must continually flow through the ignitor and oven gas valve for gas to be released into the oven burner to create a flame.

    It should usually only take in the area of 30-90 seconds for the oven ignitor to reach the proper resistance to allow the proper amperage to reach the gas valve to open it and for the ignitor to ignite the gas at the oven burner.

    Gas stove


    The JGRP17 (not a full model number) does not have a pilot light. It uses glow bar ignitors. Watch the burner at the top of your oven when you turn on broil. After a short time the glow bar ignitor begins to glow, and a short time after that the broiler burner should ignite. The same thing should happen with the oven burner under the floor of the oven when you attempt to bake. If the igniter does not glow, or glows and burner does not light, replace ignitor. (looks like part # WB2X9154)
