Having problems with your Air Conditioners ?
Furnace lights but flame goes out almost immediatley
It's the limit switch that is located on the fire box. There are two wires that go to a disk about the size of a penny and in between the two wires is a very small button. This button resets the limit. If this switch is tripped, the flame will immediately go out to protect you from carbon monoxide poisoning and possible fire. If it will not reset, then take the two wires off and use another piece of wire to jump the switch. If it lights, then you know that the limit is bad. If not, then there are a few more to find. There could be 2 to 3 of these on the fire box and there is usually one near the inducer or on the inducer.

I am looking to buy a house in forclosure. It has a Tappan gas furnace about 9 years old and there is no manual. Can you advise as to whether the following problem is serious and estimate what the cost of repair will be? Exhaust blower is always on; red light on circuit panel is constant. Then gas flame is ignited and burns for a couple of seconds; yellow light on circuit panel comes on. When blower motor begins, gas flame goes out, yellow light goes out, and red light repeats sequence of 2

I have a ruud furnace/airconditioner Model:UGPN-07EAMER, Serial: FU5D302F390401344. When the thermostat calls for heat, a little motor (within the furnace itself) or something kicks on, the burners ignite a few seconds later, then the blower starts. It's at this time the flame goes out and the blower is just sending cold air throughout the house. There are two green lights (power and ok) lit normally and the orange(ish) blinking "flame" light on the main board. When the flame goes out, the

My bosch 21E (infinity style) hot water system has an intermittant fault where the flame does not appear to be able to stay on (or properly light). Once water is started to the unit I can hear the ignitor go on and the fan start (and I think I can gear the flame light too) but then almost immediately it sounds like the flame goes out and tries to reignite. It never actually lights properly though, just continues the same ignite-fan-flame out-ignite cycle. After a while (a day or so) it seems to

My ventless gas heater has an uneven flame with orange tips, the flame toward the outer edge is higher than the flame in the middle, and also,when I light the heater, it doesn't just give me a piolot light, it lights the row in back on low, flickers, and has an unstable flame and then you turn it to low, and it goes out until you turn the regulator knob a little higher, for more heat and it goes out completely, all except the piolot light

I think you have a bad thermocouple. The thing your lighting should be the pilot(otherwise you got a bigger problem and you should definitely call someone). The thermocouple senses heat so if it's bad it won't send the signal to the gas valve to ope ... Air Conditioners
