Range Repair Tips and Solutions
- Enter the range ERC’s Fault Retrieval Mode to display the hidden fault codes (see unit’s Mini-Manual). Fault code F350 will likely be displayed. This indicates the ERC has detected the cooling fan blower wheel is not turning as fast as it should or is not turning at all.
- After cycling power to the range, enter the ERC’s Service (Test) Mode. Activate the cooling blower at low speed for a few seconds by pressing ‘3’.If the blower, which is visible through the vent trim at rear of maintop, fails to spin or spins very slowly, investigate the cause by removing the range maintop. Inspect the blower wheel for obstruction by wire routing, foreign objects or insulation pressing on the red silicone hub of the blower wheel and repair as needed. The blower wheel should rotate freely by hand without noise or undue friction.
- Verify wiring connections to the low speed (black wire) and high speed (red wire) tabs of the blower motor. Verify wiring connection to the Neutral (white wire) of the blower motor. Verify the gray plastic 6-pin connector is completely connected. If either of these checks fails the problem is in the wiring or connectors going to the blower motor.
- Reactivate the cooling blower in the Service Mode and check for 120 volts AC to the low speed tab (black wire) and the neutral tab (white wire) of the blower motor (see strip circuit below). Check for good connection and voltage at door lock motor switch and J903 pin 1 on RC17 machine board on rear of unit. If 120 volts is not present from J903 pin 1 to neutral when cooling fan is on in service mode, replace the machine board.
- Disconnect power and check for resistance between white to red (~ 31 ohms) and white to black (~ 47 ohms) on the blower motor. If all wiring checks are correct and the blower wheel rotates freely, replace the blower motor assembly (BLOWER TANGENTIAL - WB26X29060) by removing the four hex-head screws that attach the assembly to the blower shroud. The upper back wire cover and the right side panel will have to loosened to remove and replace the blower assembly.
