SYMPTOM

 

POSSIBLE CAUSES

 

 

 

No steam generation but cavity fan

1.

Cavity temperature is above steam temperature set point

operates.

 

and oven is performing automatic cooling before steam

 

 

generation can start.

 

2.

Water supply off.

 

3.

Steam generator thermal fuse(s) open.

 

4.

Steam generator heating element(s) malfunction.

 

5.

Contactor(s) malfunction. See “HEATING MODE AND

 

 

CAVITY FAN SPEEDS” under “ELECTRICAL

 

 

OPERATION”.

 

6.

Lime scale build up (moist) on water level sensors giving

 

 

false reading. See note at the beginning of

 

 

troubleshooting section.

 

7.

Oven control board malfunction.

 

 

 

Oven displays “888F” or “888C” in the

1.

Cavity temperature probe.

temperature display.

 

NOTE: On 10 level machines - error in the single cavity

 

 

temperature probe. On 20 level machines - error in the

 

 

upper cavity temperature probe.

 

 

A. Damaged probe or thermocouple lead wire open.

 

 

B. Board connection loose or connector not inserted

 

 

onto board properly (mis-aligned).

 

 

C. Thermocouple lead wires reversed. When heating,

 

 

cavity temperature will appear to decrease for

 

 

several seconds, then error code will display.

 

2.

Low or no voltage on battery backup to maintain controls

 

 

setup and program information in SRAM. See “BATTERY

 

 

BACKUP - PROGRAMMABLE CONTROL” under

 

 

“SERVICE PROCEDURES AND ADJUSTMENTS”.

 

3.

Incorrect temperature probe in use. Ensure the

 

 

temperature probe is not a thermistor type by checking its

 

 

resistance. If resistance measures approximately 110

 

 

ohms at 70-80°F then do not use.)

 

 

 

Oven displays “999F" or “999C" in the

1.

Cavity temperature probe.

temperature display.

 

NOTE: On 10 level machines - error in the single cavity

 

 

temperature probe. On 20 level machines - error in the

 

 

lower cavity temperature probe.

 

 

A. Damaged probe or thermocouple lead wire open.

 

 

B. Board connection loose or connector not inserted

 

 

onto board properly (mis-aligned).
