Every two weeks it starts beeping and both ovens stop working

Disconnect the touch pad from the ERC, if unit starts to beep after doing this it is a problem with the ERC, if not it should be the touch pad. Unfortunately this will disable the oven but at least you can get it narrowed down before you replace a $300 clock.

ERC Quick Test
The process requires two people. To access the program, one person should stand at the oven, while
the other is located at the circuit breaker. The person at the circuit breaker turns off the breaker and
then the person at the oven depresses and holds the cooktime keypad. The person at the circuit
breaker then turns the breaker back on. The display will show the 4-character identification code of the
ERC. Example (1180)
You have 30 seconds between each test mode.
Note: if unit shows time of day start procedure over again.
Test 1
Push and hold convection bake
Bake element and convection fan activate.
Test 2
Push and hold Standard Bake
Bake element activate.
Test 3
Push and hold Pure Convection
Convection fan and convection element activate.
Test 4
Push and hold broil
Broil element activate. (on gas units – ignitor will activate.)
Test 5
Push and hold convection broil (select models)
Broil element and convection fan activate.
Test 6
Momentary push timer 2
Audible tone will sound.
Test 7
Push and hold stop time
Cooling fan activate.
Test 8
Momentary push clock
All LEDs will light up. Push + or – key pad. LEDs wil display numbers
Example: 1111, 2222, 3333, 4444 etc.
Test 9
Last test door open, push and hold cook time for 10 seconds
Self clean latch motor activate. Door latch will complete one cycle.
The test will end and ERC will display the time of day.
NOTE:
Complete all tests within 30 seconds – otherwise you will see a failure code (F-0: Stuck key pad) displayed
on the ERC.

OUTPUT VOLTAGE CHECK POINTS
ON ERC/CLOCK CONTROL
All Ranges And Wall Ovens
When programming the oven into a cooking cycle, you first select the desired mode on the
touch membrane. Pressing this key sends a message to the ERC/Clock control, which in
turn triggers 24 Volts DC to be sent to the main relay board through the connective harness.
The desired relay (for example, Pure Convection) closes and distributes power to the
desired components. In order to correctly diagnose this sequence you need a volt meter
set on DC voltage. Drop the Bezel/Control panel down thus exposing the ERC/Clock and
related wiring. Dropping the control panel down will expose the back side of the ERC/Clock
control and main wiring harness. The connective harness will have 16 pins. Using a voltmeter
take the test leads and insert into the backside of the main wiring harness
To take a voltage reading using the ERC connection chart below:
1. Set the voltage meter to DC voltage
2. Insert the test lead into the backside of the main harness
(plugged into the backside of the ERC control.)
For example: if bake isn’t working:
a) Insert the test leads into connections (2-5)
b) Program the unit into the bake cycle
The meter should read 22-24 Volts DC
