What do you get for an error message when it shuts down?

Customer reply replied 3 months ago
No error messages. It simply cycles through purge, ignition, run...over and over
Customer reply replied 3 months ago
It's been doing this for some time. I can usually convince it by choking the air intake and getting a good solid ignition. But not any more.

When was the last time is was serviced?

Customer reply replied 3 months ago
I serviced it last year with a WM servicing kit (gasket, ignitor, etc). I've had it open this morning and cleaned it again. Took some emery cloth to the ignitor. There was significant moisture in the chamber so I dried it out with a hair dryer, something I've had to do before.

Sounds like a clogged condensate drain

I checked it. It's not.
Customer reply replied 3 months ago
At ignition I see flame in the window. If I choke it I can get a more robust flame. But then it goes out.
HVAC Technician: Rick, HVAC Supervisor replied 3 months ago

I'm going to open this up to my colleagues so one of them can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.
