 Gibson Gas valve?
i have 3 yr old gibson(nordyne) GL1RA 090C 12B and i now have no heat. led flash 4, inducer runs, ignitor glows, then shuts down without a flame. 4 or 5 tries later shuts down flash4. i think the main board may be faulty, with the wires removed from the gas valve i get 11.4 volts across the bwn and yel wires. when the gas is demanded (after ignitor warm up) the voltage drops to 0 v. am i correct in thinking this two wire gas valve should have 24 volts when commanded open and 0 volts off?? with the valve plugged in i get .26 volts off and 0 volts when commanded across the two wires on the main board connector. anyone seen this? or have a recommended test for me to try?
gas valve coil resistance 2.04 M Ohms
i recently replaced the inducer vacuum switch, it was sticking and gave a a flash 3 about 2 months ago
