Testing Procedures

!WARNING

To avoid the risk of electric shock, personal injury or death, disconnect power before servicing, unless testing requires it.

Service Information

The ERC operates in conjunction with a separate relay/ power supply circuit board, and oven temperature sensor(s) to control all bake, broil, convection, and self clean functions.

The ERC is connected through to a function panel to control minute timer, clock, stop time, oven light, panel light, cancel, bake, cook time, broil, convection bake, convection, convection broil, and clean. Slew pads are used to set times and temperatures.

The mylar control panel provides direct input to the ERC to control all functions.

The ERC display consists of two digital readouts which displays all timing functions, and all temperature functions.

The relay/power supply circuit board consists of relays for convection fan, oven light, convection element, bake, broil, door lock, and double line break operations controlled by the ERC, and a step down transformer with two secondary windings which convert 120 VAC input to filament voltage to power the ERC display.

The oven temperature sensor is mounted in the oven cavity and connected to the J4 connector on the rear of the ERC. As the oven temperature increases, the sensor resistance also increases. The ERC converts this resistance change to a corresponding temperature readout and to cycle the relay(s) to maintain the desired temperature setting.

The ERC is also capable of sensing certain failure conditions which can occur in the oven temperature sensor(s), the self clean latch switch(es) the adaptor board or the ERC itself. If the ERC senses a failure, power will be removed from the relays, an alarm will sound and a failure code will be displayed.

Each major component of the Electronic Range Control system is serviced as a separate part. However, each component and related wire harness must be tested prior to replacing an individual component.

Quick Test Procedure

“Quick Test” Mode for Electronic Range Control Follow procedure below to use the quick test mode. Entries must be made within 32 seconds of each other or the control will exit the quick test mode. The quick test mode cannot be reactivated until power is disconnected from oven, and must be accessed within 5 minutes of powering up.

NOTE: To enter Quick Test mode, this must be the first key pad entered after power is applied.

1.Apply power to oven press and hold COOK TIME pad for 5 seconds.

2.Display will read the following:
