I have an NT 30 SP, and I think I have it narrowed down to the circuit board failure. I just don’t know how to take the shell off to access the circuit board. How do you do that?
I haven’t figured out yet..hoping someone has some input soon. My furnace is completely out now and the blower isn’t working. I can hear the thermostat engage and click but now the blower does not have power.
Great video. I’ve got an NT20 that the blower won’t even kick on. I pulled the unit out, but as you’ve noted in the video, I can’t even access wiring to test for power. Pulling the cover off my thermostat, it appears that the t-stat is functioning, but how can I be sure? What else should I be checking to see why the blower isn’t coming on?
Three sail switches, three relays, two limit switches, new igniter, new gas valve and two boards it ran perfect for a week. Now it only runs good in manual mode. I have to shut it off before it try's to restart in auto or it will only blow cold air ,not lighting. If not then I have to unplug connector to work again in manual mode. Looks like a third board is needed. Over 1000k invested in this furnace. From me replacing parts, to a worthless tech replacing parts, To a shop that by replacing parts finally got it to work right for a week. Such is my story with the NT30SP.
You have a leak. Use soapy water at your gas fittings to find where. When the line is pressurized gas will escape at the leak and soapy water will bubble.
Thank you for this Video! You’re super smart my guy. Very good teacher.
Great video, short and sweet. Thank you.

How did you get its shell off

Getting the shell off is generally one or 2 screws- one on each end under the covers where the foot holds it to the case

Blower not coming on can be a stuck on sail switch, blown fuse , bad blower, no command from t-stat or board issue
I have the same exact problem. What did you find was the problem??
My sf series unit stopped working after using for 2 days. I have propane but the blower won't go on.
It appears the fault was in the circuitboard

Jumps around too quick.
