Do I need a outside cooling unit for a Coleman 7900 Presidential lll gas heat and cooling unit


Yeah, youd have to look at the model on the Indoor coil box, furnace will be setting on top of it. Youll need the model off that coil box to get the correct tonnage of the outdoor condensing unit, you can go 1/2 ton smaller on outdoor for greater efficiency.

Older coleman furnace in mobile home model 8631a was called by older couple who own it. Was told that standing pilot has gone out twice within two weeks never had problem before. Questioned owner if...


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.

Im trying to figure out how to light my neighbors 7900 series gas furnace. Followed instructions pressing pilet light etc. Just cant figure where to ignite inside furnace door.


Hi, Just follow the pilot light tube back, the aluminum tube, back under to where it stops at the pilot burner. You may need to open the door to reach back there or you may have that piece of metal that you put the match in to reach back far enough to light it. Just turn the knob to pilot, and hold it down and you should be able to hear and smell the gas. Light the match and stick it along side of the pilot tube at the very end and it will light as long as you hold the knob down. After it lights hold it for about another minute and release it slowly. It should stay light. If not wait 5 minutes and try again. Very easy to do when you follow the tube that supplies gas back to the pilot, that's where you stick the match or lighter. Look back there with a good strong light and you can see where the tube stops. This is where the gas comes out. Please let me no, and don't forget to rate me as I know you will be kind. You will find it. If you can't get it, you can call out your local gas company and they will light it for free of charge, no cost to you.

The Pilot on my electric furnace will not stay lit, blowing cold air instead of warm. The model is L8T-UH.


Is this a code for us to come over cause electric furnaces dont use a pilot light ha! Ha! (they uses electric heat strips for heat .....but if you want to give away money..........)

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!

I had a similier problem, Check your neutral ground? also alot of power companies will come out and do a basic check of the voltages going to the furnace, and can offer advice for free.

Pilot light is out of our coleman 7900 mobile home furnace and we can't get it re-ignited


The thermo couple or the gas valve itself is most likely bad. Cheap enough to start with the thermo couple.
