Hi there! Can someone please help! I have an ancient (1987) Caloric electric range, model ERR-389. It is a combination "ME" range that microwaves and cooks in the same oven cavity. Very space age and rare and I want to keep it working if possible....
Anyway, the oven seems to be off by about 20-30 degrees lower than what it's set at. It seems more accurate at higher temps, but at lower temps it's really off in its calibration.
The problem is that the digital low temp oven sensor 'thermocouple probe' (Part 0064074 or Y0064074) is NLA from everyone I have checked with, and I have no clue whether it is possible to manually adjust the calibration on this thing. (The oven also has a separate, high-limit, bulb-type thermostat that somehow separately controls the self-clean cycle). The range has a digital glass touch control panel that controls the oven and also the electric burners. It does not seem to have any built in diagnostics, however (it doesnt show error codes, etc., like new digital ranges do).
Is there some way to re-adjust the range temperature? The owner's manual says nothing about re-calibrating the temp. Is there a screw somewhere to turn or is there something like a jumper pin on one or more of the control boards behind the control panel, or down on one of the other relay/CPU boards located below the oven? (There are about three or four separate relay boards in this this thing). Or possibly a special combination of key presses?
Or is the only way to fix this to get a new sensor? And how can I do so if it's NLA....
Finally, is the sensor even truly broken or is this temperature inaccuracy actually considered 'normal'.
