At the beginning of this season my 5 year old Enviro Mini shuts down 5 minutes after firing and the #4 light (2nd from top), blinks. Reset and it runs for an hour or so before it shuts down and the same light flashes. Lately, it shuts down before firing, with the same light flashing—no fire-no heat. Reset Sometimes produces fire, but it is short-lived.
Any help?
