Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am APPLIANCE-HVAC GURU a very experienced tech on here and I try to get to as many customers as I can. I just picked up your question now.

Please allow time for me to respond, sometimes I get the questions or responses late so please be patient as I have no control over the site issues. NOTE, I have nothing to do with your payment to the site and did not receive that money.

It is not that big of a job to you do not need to remove much to get at the flame sensor on the unit, can you see it?

Customer: replied 1 year ago.
I can see the flame sensor but don't know how to get to it.

Can you just get at the single sheet metal screw under the unit to bring the assembly down and out?
