Howdy Furnace folks! OK, my turn in the barrel again.
We have a York furnace, I think about 13 years old. I replaced the filter yesterday--all very well intentioned, I assure you. We quickly noticed that, today, it ain't workin'! There is not a sign that it is receiving power at all.
Model # is P2MPD20N11201A. (Is that a long enough model number or what!)
This has actually happened before. It's easy to knock loose a wire in the fan compartment when changing filters. The wires are to the upper right of the fan, and are red and yellow.
I believe RED goes on TOP; YELLOW on BOTTOM--as the wires were just loose right over these positions. I rehooked them, and no luck.
I have recycled power and thermostat settings; also no luck. The gas is electronic ignition, but I have also turned this off and back on with the light blue knob.
Any ideas welcome! Especially before it gets too cold again! Thanks in advance!

An update:
1. There is a fuse compartment for the furnace. There was no fuse before, and it's been working this way for years. I tried putting a fuse in; this didn't do anything at all.
2. The red and yellow wires I mentioned: These go to two small units--possibly temperature sensors?--one left and one right, above the fan. The protrude into the area below the heat exchanger. The only one that was knocked loose was the one up and to the right.
Your ideas please! I could put in a service call, but would probably have to wait till Monday to save the big overtime dollars.
Thanks!

Hi HK, thanks for your reply!
First, I guess I should say, hey, I didn't know you had become a moderator! Congratulations! (I think :) But seriously, long overdue, good to see it!
I would believe the board has blown; this has happened before a couple of times. I will put in a service call; probably be Monday or Tuesday before anyone will even answer (given Christmas).
In the meantime, we stoke the fireplace and try to stay warm the old fashioned way! Not so bad really, up to 56 degrees inside as we speak. Better than the 49 this morning!
Speaking of those 2 switches--or sensors (if that's what they are), in the fan compartment right below the heat exchanger: as they only have 2 wires, would it have done damage to reverse these? Just curious. Obviously, I have more at issue than this at the moment!
Take care HK!, thanks again for your reply!

Hi HK,
You were right, was the transformer. Fortunately, the circuit board was OK--much cheaper.
Take care!
