Can anyone tell me where the Igniter is located on a Trane XE 80 Might you have a picture that might show what it looks like. Thanks

The ignitor is near the burners... are you thinking that is your problem? If you list more information we may be able to narrow your problem down. If ignitor isn't glowing when supposed to the board could also be bad... Let us know.

The problem is when I went to bed last night the heat was working fine and when I got up in the morning the blower was on but no heat. I turned the thermostat off for 5 min and turned it back on to find that the blower was on with no heat. So I am assuming the igniter did not work to lite the burners. So I need to know where the igniter is located and what it looks like

Thanks

If the blower is running consistent then the high limit is stuck open or one of the auxiliary limits has been tripped.

Is there anything I can do tonight to get the heat on manually?

Thanks

Do you have a multimeter?

No don't have multimeter

Auxiliary limits are basically wired in series... they are about the size of a nickel or dime and have a resettable pin in between the tabs were the wires attach. Look for one of those that may have been tripped. If one of them was tripped you may have a bigger problem and I would recommend a qualified technician.
