Questions & Answers

For Whirlpool Cooktop Fan Control Switch (Part Number: OEM18033354)

Dave for Model Number CVEX4370B

I have a fan that the knob broke off flush with part of the post so the fan will only work when the grill is turned on. It looks like the fan switch is part wp74009256 ( my actual part # is 7403P438-60) (Y2510A) I have 2 blue wires, 1 black wire and 1 grey wire but it looks like that replacement part on has 2 slots to connect wires. will this part work and if so would I need to rewire several wires together into new connectors? will the fan function on multiple speeds if I replace it?

Dave, We will need to have the first 2 digits of the serial number to determine the correct fan switch for your model.

Harv, To access the fan switch you will remove the cartridges from either side of the control panel, remove the 2 screws on either side then lift off the control panel.

Andy, it would be recommended that the wires are inspected for any bare sections that are touching as the only way for the fan to get voltage would either be through the switch or through bare wires touching.

Andy, We are not showing a red wire to the fan switch and it is possible that your model has a serial number that starts with a 10 and that the fan switch you received will not work. The fan switch that you would have needed in that case would be 71001303.

Hello Randy. Remove the air grill and switch knobs. Remove the 2 phillips head screws securing the escutcheon to the blower plenum. Lift out the escutcheon. Remove the 2 11/32" nuts securing the fan switch. Disconnect the wires and replace the switch. Thank you.

Reens, Based on our information, Yes, the WP74009254 / WP74009254 Fan Switch should fit and work in your CP320B Cook top control panel. You may also need the WP422617 / WP422617 Mounting Nut to mount the switch to the control panel. If you have the original fan switch in the unit, you'll find it easier to remove power to the cooktop. raise the control panel housing from the outer housing, remove the original switch and wiring, from the housing. You will only need the two(2) black wires the L1 common black wire and the black wire to the down draft blower motor. Attach the wires to the two terminals on the fan switch, reinstall the control panel assembly, restore power and check the blower motor operation.
