Trane Self Igniter Problem


I have a Trane XB90 that has stopped igniting. When the thermostat sends a call to run, the fan comes on, followed by the glow bar. Gas apparently does not flow, so glow bar shuts down. After a few seconds, glow bar lights back up but with same results. I've turned the valve off for 5 min and then back on as directed, but with no change. I believe the unit is about 7-8 yrs old, but to me, it looks new inside. Any advice?

Trane Self Igniter Problem


you need a meter to check across both terminals of the gas valve to see if it's receiving 24 volts.

sequence of operations for a draft induced gas furnace:
1.) inducer (exhaust ) motor starts
2.) pressure switch proves burnt fumes can exhaust by way of pressure switch closing
3.) ignitor lights up
4.) gas valve is sent 24 volts to open, fire starts. there is a distinctive click when the gas valve receives it's 24 volts, after the ignitor is lit up. again, you need to check across the two terminals where the two wires connect at the gas valve for 24 volts. remember, it will only be sent 24 volts once the ignitor is lit up
5.) appr. 30 seconds after burners have lit up and the flame sensor has noticed the flame and they continue to burn, the main blower begins to run.
