Bake and Broil operations shut down when temperature reaches

approximately 250F.

If the selected bake or broil function operates briefly, then shuts down, the problem is not likely

with the ERC. A problem may exist with the cooling blower motor or the motor wiring.

Models affected:

C2S995SEL, PGS960BEL, PGS960EEL, PGS960FEL, PGS960SEL,

CGS995EEL, CGS995SEL

Serial numbers: All

Repair Procedure:

1. Cycle power to range. Press and hold ‘2’ and ‘Bake’ simultaneously for three seconds to

enter Fault Retrieval Mode. Press ‘1’ to display stored faults. Fault code F350 or F352

will likely be displayed. This indicates the ERC has detected that the cooling fan blower

wheel is not turning, or turning too slowly.

2. Enter the ERC’s Test Mode by pressing and holding ‘1’ and ‘Bake’ for three seconds.

Pulse the cooling blower at low speed by pressing ‘3’. If blower wheel, which is visible

through the vent trim at rear of maintop, fails to turn, service is required.

3. DISCONNECT POWER. (LOTO) Remove:

•Grates and top burners

•Rear spacer-to-wall trim

•RJ45 connector from square hole

in upper corner of rear wire cover

with a flat screwdriver

•Backguard complement strip and

upper rear wire cover

•Vent trim

•Maintop

•Fan motor spill guard to access the motor’s electrical connections (see picture

above)

continued…

Ensure that proper clearance

between wires and blower

assembly will be maintained

when rear wire cover is re-

installed.

Remove the three hex screws

securing blower and lift blower

and duct assembly. Push

insulation beyond vertical

flange of oven cavity.

4. Check for foreign objects in the blower wheel. The wheel should rotate freely by hand

without noise or undue friction. Be sure nothing is pressing against the red hub on the

end opposite the motor. Re-route any wires, such as the RJ45 connector leads, that may

lie in contact with the motor shaft.

5. Visually check wire connections to the low speed (black wire) and high speed (red wire)

tabs of the blower motor. Check connection to the Neutral (white wire) tab. Make sure the

gray plastic six-pin connector is fully engaged.

6. Power up range. Check for blower operation again using Test Mode (Step 2). If blower

now operates, look for insulation pushing up on blower that would cause binding when fully

assembled.

continued…

7. Press ‘3’ again and, if still no operation, check for line voltage between the low speed

(black wire) and neutral tabs. Also check for line voltage at the ERC between J903 pin 1

and neutral. If line voltage is not present, DISCONNECT POWER and replace the

MACHINE BOARD WITH FRAME.

8. If line voltage is present, the BLOWER TANGENTIAL –WB26X29060 will have to be

replaced. Normally, the green sensor circuit board attached to blower motor will be good

and can be reused.

9. DISCONNECT POWER. Loosen the upper rear splash guard. Remove the three Hex-

head screws circled below to loosen side panel.

10. Disconnect three leads from motor and unplug six-pin connector. With a ¼” ratcheting box-

end or open-end wrench (arrow), remove the four hex-head screws that secure the blower

assembly to the duct. Carefully work blower assembly out of the duct.

If holes aren’t aligning easily,

consider leaving out the two screws

indicated. Driving these screws

under tension may deform ducting

and cause blower to bind.

11. Transfer the sensor circuit board from the defective blower to the replacement blower.

Connect the sensor circuit board and connect wire terminals to motor tabs. Carefully

work blower assembly into place and attach to duct by replacing the hex-head screws

in the order indicated in the photo above.

12. Power up unit. Check for blower operation as per Step 2. DISCONNECT POWER.

13. Replace:

•Hex-head screws in side panel and the Phillips screws in rear splash guard

•Motor spill guard

•Maintop

•Vent trim

•RJ45 connector to square hole of rear wire cover

•Backguard complement strip and rear wire cover

•Rear spacer-to-wall trim

•Top burners and grates.

•Power unit and check for cooling blower operation one more time per Step 2. Start a self-

clean cycle and listen for rattles with fan operating at high speed, then cancel self-clean

operation.
