550 degrees and shuting down

you didn't say how old it is, but likely going to a competent and trained repairman might be the real solution.

CHECK THE ELECTRICAL WIRING.

the shutting down problem can be caused by:

1. dirty processor radiator
2. power supply problem

clean your radiator and restart your pc, if the problem was not solved check the power supply.

5.0 L with a 4bbl carb Fed. = 12 degrees btdc @ 800 rpm

cheers mate !

Sounds to me either a low refrigerant charge or low air volume over the evap coil (inside). There is a sencer for temps outside maybe it's tripping out on that.

if you read your tappan instructions, it will tell you to turn your oven to 550 degrees, then press and hold the bake button for 15 seconds. it will blank out and go to 0. adjust temp up or down accordingly. peace out.

On most ovens, set the oven temperature to either 500 or 550 degrees. Press and hold the bake button until the display changes. (5 to 10 seconds). then press the up/down buttons to adjust the the temp between + 30 to - 30 offset.
