1-4. ERROR CODES The controls have some self-diagnostic error code capabilities
that will show on the display .
Display Cause Panel Board Correction
“E-4” • Control board too hot;
cooling fan clogged or not working
“E-6” • Temperature probe
failure
“E-41” • Scrambled memory
• Turn switch to OFF position, then back to ON; if display still shows “E-4”, the PC board is getting too hot; clean louvers and check cooling fan; if cooling fan is not working, have it replaced; once panel cools down, the controls should return to normal; if “E-4” persists, replace the PC board
• Turn switch to OFF position, then back to ON; if the display shows “E-06”, temperature probe should be checked; once the temperature probe is repaired, or replaced, the controls should return to normal; if “E-6” persists, replace PC board
• Turn switch to OFF position, then back to ON; if the display shows “E-41”, the control should be re­initialized (see Special Program Section in Operator’s Manual); if “E-41”persists, have PC board replaced
“HI” • Software hi-limit;
air temperature too hot
• Turn switch to OFF position, then back to ON; if display shows “HI”, the heating circuits and temperature probe should be checked; once the unit cools down, the controls should return to normal; if “HI” persists, replace PC board
