furnace problems

[graham]

Colman evcon mod.#7121-5906. My pilot light wont turn on, its self igniting and I have tryed sevrel times with no luck. The blower still works, we have gas, its still getting power. Iv also noticed that a yellow light turns on just under the green one. Any Idea what that means? Please help its cold!!!!!

Hi,

That is not a valid model number, please look for a data sticker or nameplate on the furnace facing to get model number.


Thanks,
