I assume that this is a rather old unit if it still has a pilot light. If the pilot will not stay lit, genrally the thermocouple is the culprit, however it could be the gas valve as well.

Why would the flame and pilot keep going out changed the thermocoupler


Remove the cover over the burners so an inspection of the heat exchanger is a bit easier. Take an LED flashlight and a small telescoping mirror and inspect the heat exchangers front section above the burners giving special attention to the two sections of the chamber on either side of the pilot light. Many times there will be a hole in the chamber or a crack that will allow the blower that circulates the air into the duct blow out the pilot light.

If you are handy enough, consider turning off the gas and remove the ribbon burners prior to performing your inspection. The pilot assembly is probably attached to one of the burners. Lay them on the floor in the order in which they install in the furnace as some furnaces have dedicated left and right end burners and most older standing pilot furnaces have the one burner with the pilot mounting bracket.

To remove, many times you gently pull backwards towards the gas manifold while raising up on the front of the burners. Once elevated enough, the burner then slips off the brass spud (orifice) and forward and out.

The next reason the pilot can go out is because the safety 'holding' coil in the gas valve is defective. Its responsibility is to hold open electrically a safety circuit proving the pilot gas is burning so that main gas can flow. The thermocouple generates just enough electricity to hold the safety coil open. Coil bad = pilot out.

If your furnace is over 25 years old, there is a good chance there is a hole or crack.

Sounds like the rollout is being tripped from the blower moving the falmes. i would have your heat exchanger checked for cracks or holes as this is usually the reason the blower moves the burner flames to tripp a rollout.

Thats a safety.

The unit senses a failure to ignite, so it goes into safety mode keeping the blower running to prevent overheating and fires. And keeping the inducer motor running to prevent the same, as well as raw gas build up inside the unit.

The newer systems are "smarter" and can detect more specific problems and failures. The older ones simply know that the thing didn't light, so they bring on the fans for safety.

if it has a pilot, you can follow the pilot tube from the gas valve back to the burner assembly and find it. It may not have one and if this is the case, the air flow switch is supposed to close when the inducer fan comes on . If the flue is clogged, condensation in the bottom of inducer fan(would hear cracking). then after the draft safety switch is closed,the gas vavle will get 24 volts and allow the gas valve to open

Furnace pilot problem


check the pilot gas pressure, might be too weak and blowing out when the blower starts, the clicking noise is the gas valve shutting down when it detecks no pilot flame, that park is normal.

Rheem gas furnace pilot lights, but no burners or fan


If the burners do not fully ignite, the sensor will shut the furnace down. The lack of sufficient burner flame is a gas valve or gas pressure problem within the valve.
Replacing the gas valve with the original one may get you going. I surely suggest a professional service company for safety reasons and a thorough inspection. A 20 year old furnace is past it's normal life span.
