Good catch! Inspect the WHOLE board for cold solder joints, and surface-mount resistors making bad contact.

Ok. I checked & cleaned the sensor ( witch I am assuming is also for the heater control outside temp display that does work on the king ranch ). I reflowed all of the solder joints just to be sure, and it still does the same thing ( -40/ ice ). So for now I fixed it using my redneck ingenuity. A little electrical tape over the temperature display and fixed (for now). Ha ha

Thanks for the help everyone!

I'll take a look at the schematics when I get home

ibd2328, my unit doesn't work at all (quit just today) and there are no aparent bad solder joints. Is it possible it's tied to a fuse?

Is yours completely out?

I bet your ambient temp sensor is off.

It doesn't always look apparent. Just hit them with a solder gun & just a little solder. You'll be back in business.

Thanks everyone I took a second look at the board and finally found a cracked solder joint. Got the solder gun out and 5 minutes later it's fixed.
This forum is great and everyone helps each other!

hamilton, have you tried unpluging the sensor?

I have a king ranch with a temperature display on the heat & cool controls also, and that works. Is it the same sensor for that, or are there 2 separate sensors? I have not unplugged the one in the grill though.
