Question about Heating & Cooling

Open Question

I have an older Miller CMF80 gas furnace in a duublewide mobile home. My pilot light keeps going out after a heating cycle. I can light the pilot, and it stays lit. Once burners kick on during a heat cycle, once they turn off, the pilot also goes out. I have run the fan without the burners on and the pilot stays lit. The gas valve also is warm to the touch. I recently had to change the gas valve transformer.. Any thoguhts.

SOURCE: gas furnace wont stay lite

I'm a little confused by your terminology. You are saying you have a pilot lite and electric heat strips? Are you possibly meaning burners? Is the heater running for 2 hours straight without shutting off? how cold is it there? Lastly what temperature do you have the thermostat set at and how close does it get to the temp. before it shuts off?

Check regulator on the unit.
Check pilot unit on the heater
use soapy water to check for leaks if see bubbles turn off main gas supply valve.
always turn off gas supply before any checks or repairs are made
when all else failes call your local gas provider to check heater and gas supply

SOURCE: 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.

The pilot orifice could be dirty causing the pilot flame to be too small. Unscrew the pilot tube at the pilot assembly. The orifice is inside. Remove the orifice and blow it out with compressed air only. Reassemble and see if that fixes the problem. If the pilot flame is set too low, sometimes opening a door will cause a draft to blow out the pilot. If the thermocouple is good and the pilot flame is set properly, the control valve may be bad.

How to light pilot on Dayton furnace and then start furnace


If this is a standing pilot system, turn the gas valve to pilot position. push in the knob & hold while lighting pilot...keeping holding knob down for a minute... this will pick & hold the gas valve. Let go of the knob & see if the pilot stays lit, if it does, then turn the knob to on position & the furnace should start if there is a call for heat from the thermostat

There is a coulpe of reasons that the pilot would go out.
1. Thermocouple is dirty, try cleaning it.
2. Thermocouple is no in the pilot flame. Look and make sure it is directly in flame.
3. Pilot dirty. Flame has to be blue not yellow.
4. At the gas valve the thermocouple comes to it. use a wrench, usally 5/16ths, or 3/8s in. and make sure thermocouple is tight going into gas valve.
5. WORST case is that the heat exchange is cracked and blower motor is blowing it out. Hope this helps. thank you.

Why heater coils glow?


It sounds like you're describing one of two things. The hot surface ignitor in a gas-fired furnace, or the resistive heat strips in an electric furnace.

The hot surface ignitor in a gas-fired furnace lights the burners. This ignitor in modern furnaces serves the same purpose as the standing pilot flame did in older furnaces. It provides the required heat to ignite the gas at the burners. Without an ignition source, a gas-fired furnace cannot provide heat. When the ignitor is activated it will glow bright orange or yellow.

The resistive heat strips in an electric furnace actually provide the heat to a home or building. When the furnace turns on, the heat strips are activated and usually glow orange when they reach peak temperature. In almost all cases, the heat strips are not easily seen or accessed without removing covers or panels inside the furnace.

I have a older Miller furnace(1989)the pilot will stay lit


Replace the thermocouple.

Try this, do you have a butaine stick lighter? Try to heat the thermocouple with it ... see if you can get the main burner to come on. If not - definitely, replace the thermocouple.

Thanks for your question.

My pilot keeps going out on the furnace. We lite


Check the pilot light size. Is it small and not surrounding the top 1/3 of the thermocouple? If it isn't then the pilot orfice is restricted or the pilot tube compression nut could be loose. The pilot gas adjustment screw may also need adjusting if this gas valve has one. These problems should only be addressed by an experienced service tech.

Older heater, late-60's gas in mobile home. When furnace ignites it blows back and puts out the pilot light? Also, seems to be a delay when the thermostat clicks to come on til the furnace lights thus...


Check your exhaust pipe for blockage, Make sure pilot light is located just above or below the burner. Make sure that there is a good supply of air going to the burner and that the intake pipe (if it has one) is not restricted. A furnace that old needs to be replaced what ever you find. You could have a cracked heat exchanger.

Furnace gas pilot light keeps going out when windy outside


Honeywell makes an electronic ignition conversion kit. (White rodgers also has one but it uses a mercury switch which can be expense if it goes bad). A good service man can install the "Honeywell Y86 Universal Intermittent Pilot Retrofit Kit". This is a "complete" kit for converting a standing pilot system to electronic ignition. It includes a new gas valve, ignition cables with connectors. ignition module and a pilot assembly. It does not include pilot tubing (pilot tubing is cheap). This kit also comes equipped for either natural gas or propane. Your heating guys probably don't know about it because they are to young and not familiar with the old days. Or they just don't care and would rather sell you a furnace. I think that they just don't care. I live in Ohio I just opened up the "new" Johnstone Supply catalog. This part is "not" outdated its on page 450. Do not let these heating guys buffalo you into a new furnace. You are to smart for that! If you weren't you would have believed them and bought something you don't need. Instead of researching on the internet.
The bad news is this kit lists for $456. plus labor.
Good luck!
