    Heck Albie, if it's a light bulb out on a ceiling fan I call the office to have it replaced. Though I have had to do the ones in lamps all by myself.... :cry

    Where are you at on Mt. Sequoia? I'm on Fletcher Avenue. If you are any higher up you probably ride right by my house to get to yours.

    ok just got back from under the house.

    when heater is turned on this happens.

    inducer fan starts blow
    hot surface ignitor begins to glow

    after 20 seconds, ignitor is turned off, and it starts over again.

    no gas flow I guess?

    there is a pressure valve diaphragm thingy on the side of unit with hose going to inducer fan, could this control the gas output valve?

    I guess Ill verify gas flow into the gas valve first, then go from there.

    any ideas are appreciated.

    Yeah...if it's a newer unit ...flame detector....or what Wayno and Charlie suggest...! No signal to main valve.

    hot surface ignitor and thermo couple were rplaced last year.

    the thermo couple senses flame and lets the gas keep flowing.

    its never opening the gas on start up to allow any flame.

    I just cleaned the NPC and verified with a meter, inducer flow switches it.

    its a 10 year old unit, im looking up the honeywell control unit, to try and see whats out of the loop here.

    I suggest starting with cheapest, most easily broken part. My guess is the sensor for the ignitor. If it says the ignitor surface is not hot enough, it won't open the gas valve. Our commercial boiler at the farm gets a new sensor about every-other-year due to it's failure. Same symptom. I'd crawl under the house with you, but I didn't stay at a Holiday Inn last night.

    maybe I am not understanding what sensor you are referring to?

    there are only 2 things in the burner area

    a hot surface ignition ( glowey thing)

    and a thermocouple ( flame sensor)

    from my understanding, the control module opens gas valve for 4 seconds or so, if the flame sensor detects flame, then it leaves the valve open until the thermostat is satisfied.


    In my situation, the valve is never opening.

    glowey thing glows, then it goes out.

    no flame

    ?

    I might swap thermocouple first... Do you get a primary flame....like a pilot flame...then the main in normal operation?

    Well everyone else keeps telling me to "slow down" so I thought I would try it. I slowed down enough to wave and point out the odd fellow on the motorcycle with "Eat Me" across the brim of his helmet to my passenger. :D

    Hey Tokyo,

    If you find someone willing to do roof repairs, let me know. Everyone I have contacted claims to be too busy for repairs (or just flat turns away that type of business). However, they have plenty of time to replace my entire roof (to the tune of $10k).

    no pilot light

    only the glow from the ignitor

    no gas is ever released.

    I just jumpered the NPC sensor, same deal.

    no gas is ever released.

    I held a meter on the gas valve electrical leads, its never showing any voltage at any point in the cycle.

    The ignitor still could be the trouble, esp. if you got oil on it when installing the new one. It still sounds like some sensor (cheaper) or your circuit board (more $). Apparently the "blower" you are talking about might also be involved. I found the below on the interweb.

    Vacuum Switch
    Another common problem with pilotless gas furnaces is the vacuum switch that controls the burner. A small electric motor starts to spin right before the heating cycle, creating a vacuum, which the vacuum switch detects and then allows the furnace to start. This is done to minimize carbon monoxide and to make sure that the exhaust system is working properly. If this vacuum switch fails (sometimes the diaphragm breaks, sometimes the exhaust tube is plugged by insects or a bird’s nest outside), the furnace will not light.

    that vac switch is what I jumpered Magoo.

    I just went down there with 2 scooter batteries ( meep meep)

    and put 24V directly to to the gas valve, it clicked, but I didnt smell or hear any gas coming out.

    so now im really stunped.
