Product review (5 stars): Replaces part number 661170
This does replace part number 661170 FYI.  For the Whirlpool oven.
Easy replacement of old part - unscrew the plate, pull out, disconnect from terminals, push new one onto terminals, push back inside, screw plate back on - anyone could do it!  Save yourself a repairman call.
Don't forget to unplug the oven first!!!
Thank you Whirlpool for sticking around!!  :)
