Does the 7505 lock out when the burner is firing?

There was a glitch with your account. If you want me to call you need to contact customer service to iron it out. Or we can continue here.

You need to know for sure if it's firing up. The burner motor may start when you hit/hold the reset but if the burner doesn't fire up (firing up is unmistakeable) then you need to address the ignition failure. If you have no experience or inclination to troubleshoot this then you need to call a pro. If the burner hasn't had a tune up in a year or more it's due for one

If the burner ignites then locks out while it is firing then you either have a bad 7505 or a bad cad cell or cad cell socket.
