ATTENTION!!!

This service manual is intended for use by persons having electrical and mechanical

training and a level of knowledge of these subjects generally considered acceptable in the

appliance repair trade. Electrolux Major Appliances cannot be responsible, nor assume

any liability, for injury or damage of any kind arising from the use of this manual.

SAFE SERVICING PRACTICES - ALL APPLIANCES

To avoid personal injury and/or property damage, it is important that Safe

Servicing Practices be observed. The following are some limited examples of

safe practices:

1. DO NOT attempt a product repair if you have any doubts as to your ability to

complete it in a safe and satisfactory manner.

2. Before servicing or moving an appliance:

• Remove the power cord from the electrical outlet, trip the circuit breaker to

the OFF position, or remove the fuse.

• Turn off the gas supply and allow any residual gas to dissipate for 10 to 20

minutes.

3. Never interfere with the proper operation of any safety device.

4. USE ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE.

SUBSTITUTIONS MAY DEFEAT COMPLIANCE WITH SAFETY

STANDARDS SET FOR HOME APPLIANCES.

5. GROUNDING: The standard color coding for safety ground wires is GREEN,

or GREEN with YELLOW STRIPES. Ground leads are not to be used as current

carrying conductors. It is EXTREMELY important that the service technician

reestablish all safety grounds prior to completion of service. Failure to do so

will create a hazard.

6. Prior to returning the product to service, ensure that:

• All electrical connections are correct and secure

• All electrical leads are properly dressed and secured away from sharp

edges, high-temperature components, and moving parts

• All non-insulated electrical terminals, connectors, heaters, etc. are

adequately spaced away from all metal parts and panels

• All safety grounds (both internal and external) are correctly and securely

connected

• All panels are properly and securely reassembled

Testing Function and temperature selectors

The function and temperature selectors both use a Piher N-15 10 K ohm pot. Note that the tolerance on this part

is 30%, so the measured resistance between pins 1 & 3 will be 10,000 ± 3,000 Ohms. The controller uses a

ratiometric approach to determine position so this variation does not affect the software.

Function selector

The function selector usually fails, open or intermittent. When this happens, the oven will not operate in any

function.

To test the functions selector in the field:

1. Measure the resistance between pins one and three.

If the reading is between 7000 and 13,000 ohms go to step 2.

If the reading is not between 7000 and 13,000 ohms, the function selector is defective.

2. Set the function Selector to bake and measure the resistance between pins two and three.

If the reading is between 580 and 1720 ohms, the function selector is good.

If the reading is not between 580 and 1720 ohms, the function selector is defective.

Temperature selector

The temperature selector usually fails, open or intermittent. When this happens, the oven will not operate in

any function.

To test the temperature selector in the field:

1. Measure the resistance between pins one and three.

If the reading is between 7000 and 13,000 ohms go to step 2.

If the reading is not between 7000 and 13,000 ohms, the temperature selector is defective.

2. Set the temperature selector to 300° and measure the resistance between pins two and three.

If the reading is between 2200 and 4300 ohms, the temperature selector is good.

If the reading is not between 2200 and 4300 ohms, the temperature selector is defective.

Note: It is sometimes easier to make these measurements by disconnecting plug P9 from the elec-

tronic oven control board and measuring in the harness side of the plug. When testing the function

selector at plug P9 pins four and six should read between 7000 and 13,000 ohms and pins five and six

should read 580 to 1720 ohms. When testing the temperature selector at plug P9 pins one and three

should read between 7000 and 13,000 ohms and pins two and three should read between 2200 and

4300 ohms.
