Have a comfortmaker furnace just under 5 years old. keeps

Customer Question

have a comfortmaker furnace just under 5 years old. keeps getting a 3 flash error code. cleaning/checked the condensate system, the air intake, opened all registers, new filter, removed top cover, replaced the lp switch (I think that's which one it is - in front of combustion fan) and I'm still getting the error code. the furnance is in a very remote area so getting a tech out is extremely cost prohibitive
JA: Did you double-check the thermostat's settings? And what about the filters?
Customer: yes to both. did have a tech out and all as he could figure was it needed a new switch which was shipped and installed same as old one.
JA: Do you plan on doing the work yourself?
Customer: have to because it is located in a very remote part of Canada
JA: Anything else we should know to help you best?
Customer: while not a certified heating contractor, I am a general contractor and quite knowledgble in HVAC stuff
