Error Analysis And Elimination; Gas Operation - Electrolux RM 4185 Service Instruction

a) Preparations
The AES II device must be connected to a 230-V supply line and a 12-V supply. You must con-
nect a gas cylinder and open the gas supply to test the gas function.
b) Test execution
You must proceed as follows to arrive at diagnostics operation:
1. Switch off the device
2. Press the button for the temperature setting and keep this button depressed. Use the power
switch to switch the device on.
3. Keep the button for the temperature setting depressed until the AES operation LED switches to
red and diagnostics operation begins.
The AES operation LED is red during diagnostics operation.
A self-test for both electronic modules is first carried out, and all the display module LEDs are
controlled once. The left temperature LED then lights up. Diagnostics operation has selected the
original position.
You can select the following tests when you activate the temperature selection switch:
LED 1: All outputs are switched off, standby mode
LED 2: Mains power supply, 230-V heating cartridge is controlled
LED 3: Lifting magnet, thermocurrent adapter, and the ignition device* are controlled
LED 4: 12-V operation, 12-V heating cartridge is controlled
LED 5: Ignition device is controlled
* Important: For safety reasons, it is possible to control the lifting magnet just once. If the lifting
magnet is controlled again, you must first switch the device off and then start diagnostics
operation again.
C) Terminating diagnostics operation
You can use the power switch at any time to switch the device off and terminate diagnostics ope-
ration. If someone unintentionally forgets to switch off the diagnostics operation, the device swit-
ches back to cooling operation after four minutes.

5.2 Error Analysis and Elimination

1. Gas Operation

Errors according to priority:
Error: Fault LED flashes red
Cause 1: The lifting magnet does not remain tightened for the required 20 seconds.
The thermoelectric voltage is insufficient, and the ignition fuse closes.
Elimination 1: Exchange the electronic.
Cause 2: The spark plug fires even though there is a flame present (no flame recognition).
The electronics switch to fault after 25 seconds.
a) The connection between the spark plug and ignition cable is deficient. (Refer
to Bulletin 599 4717-69/1, Page 15.)
b) The ignition device is defective. (See Bulletin 599 4716-54/5, Pages 13-14.)
Eliminaion 2: Chance the spark plug or the reigniter.
