Turbo Chef Technologies HHB-8136, HHB-8029, HHB-8028 F7 Thermo Thermocouple Open, F8 Heat LOW

20 DIAGNOSING AN ISSUE

 : Location of Hi-Limit Thermostat Reset Button

F6: EC TEMP (Electrical Compartment (EC) Temperature High)

This fault displays if the Electrical Compartment (EC) temperature exceeds 158°F (70°C). The Control System checks the EC Thermocouple once per minute.

NOTE: This fault will not terminate a Cook Cycle.

To clear this fault:

The EC temperature must recede below 158°F (70°C).

Troubleshooting: F6 Fault

To troubleshoot an F6 Fault, see the diagram on page 21.

F7: THERMO (Thermocouple Open)

This fault will display if the Control System detects that the CC Thermocouple is “Open,” or 999°F/C.

To clear this fault:

The Control System must detect continuity on the thermocouple circuit.

Troubleshooting: F7 Fault

To troubleshoot an F7 Fault, see the diagram on page 21.

F8: HEAT LOW

This fault will display if during warm-up the Cook Chamber temperature fails to rise at least 35°F (approximately 18ºC) every five minutes.

NOTE: This fault will not log; rather it will display an Error Message during warm-up.

Troubleshooting: F8 Fault

To troubleshoot an F8 Fault, see the diagram on page 22.
