2-19. HIGH LIMIT

Step 3

SCR-6/8

The high limit is a safety device which senses an overheating situation inside the rotisserie (around 500ºF), which shuts the heat off in the unit. Once the temperature inside the unit goes down, then the high limit automatically resets and the unit can then be heated. All SCRs have two high limits. The SCR-6 and SCR-8 both have a 450ºF high limit and a 500ºF high limit. The SCR-3 has a 285ºF high limit and a 450ºF high limit.

European, CE units have 450ºF, manual reset high limits. These have a reset button on them and must be manually pressed. Follow the steps in the procedures in this section to access this high limit.

1 . Remove electrical power supplied to unit.

To avoid electrical shock or property damage, move the power switch to OFF and disconnect main circuit breaker, or unplug cord at wall receptacle.

2.Remove the side panel closest to the controls.

3.Pull the wires from the 500ºF high limit (285ºF on SCR-3s) and check for continuity between the terminals. When the cabinet temperature is below 300ºF, the high limit should show continuity. If it does show continuity, continue on with this section. If it doesn’t, replace this high limit with a new one and unit should then be ready for use.

4.If the 500ºF high limit shows continuity, the 450ºF high limit could be bad. To access this high limit, remove the insulation washer from the stud and remove the insulation.

For CE, European units, the reset button can be accessed at this time. Use a pen, pencil, or screwdriver to press the button through the hole in the box. If unit now heats, replace the insulation and side panel and unit is ready for use. If unit does not heat, proceed with the following steps.
