new hot surface ignitor, still no luck
(I apologize if this topic has already been beaten to death, but I used the keyword search and didn't come across a direct match)
My 5 year old American standard with a hot surface igniter will not fire the main burners.
The original HSI glowed fine, voltage is 120 to the HSI, but I replaced it anyway figuring it was about time and would probably solve the problem. It didn't.
The HSI will cycle about 5 times but the main burners will not ignite. Eventually the main blower will come on (still no heat), and the circuit board light will blink a code indicating that it has stopped cycling the HSI because it did not detect a flame. I can only shut the blower off by releasing the switch under the front cover.
What would prevent the system from releasing gas to the main burners?
Can anyone recommend what I should check next, and in what order?
