|
“E-4” |
Control board overheating |
Turn switch to OFF position, then turn switch back to ON; if “E-4” continues, the board is getting too hot; check for signs of overheating behind the control panel; once panel cools down the controls should return to normal; if “E-4” persists, have control panel replaced |
|
“E-5” |
Oil overheating |
Turn switch to OFF position, then back to ON; if “E-5” continues, the heating circuits and temperature probe should be checked; once the unit cools down, the controls should return to normal; if “E-5” persists, have control panel replaced |
| “E-6 A” | Temperature probe open | Turn switch to OFF position, then turn switch back to ON; if display shows “E-6”, have the temperature probe checked |
| “E-6 B” | Temperature probe shorted | Turn switch to OFF position, then turn switch back to ON; if display shows “E-6” have the temperature probe checked |
|
“E-10” |
High limit |
Reset the high limit by manually pushing up on the reset button; if high limit does not reset, high limit must be replaced |
| "E-15" | Drain switch failure | Close drain, using the drain valve handle; if display still failure shows “E-15”, have the drain microswitch checked |
| “E-25” | Heat amps too high | Heating elements drawing too much current; have heat circuit checked |
| “E-26” | Heat amps locked on | Heating elements are drawing current when controls are not calling for heat; have controls and heat circuit checked |
| “E-27” | Heat amps too low | Heating elements current is lower than expected; have heat circuit checked |
|
“E-41” |
Programming failure |
Turn switch to OFF position, then back to ON; if display shows “E-41”, the control should be re- initialized (See Programming Section) if the error code persists, have control panel replaced |
| “E-47” | Analog converter chip or 12 volt supply failure | Turn switch to OFF, then back to ON, if “E-47” persists, have the I/O board, or the PC board replaced; if speaker tones are quiet, probably I/O board failure |
| “E-48” | Input system error | Have PC board replaced |
| “E-70 B” | Faulty power switch, or switch wiring; faulty I/O board | Have power switch checked, along with its wiring; have Input/Output board replaced if necessary |

“E-92” |
24 VAC fuse on I/O board open |
Have components, in 24-volt circuit (I.E., hi limit, drain switch) checked for shorts |
