The Repair Part List from Whirlpool lists the bake element for the top oven as part #3177423 but you list it as #3177420. Is this the same part? Thanks.
Answer Ron, the original bake element (part number 3177423) discontinued and is now replaced by part number 3177420 from the manufacturer. This is our part number 3177420. Thanks!
I have an oven with the bake element that looks like part # AP3026501. I have no continuity on the element itself and when I check voltage at the connection I have 241 VAC at start up and drops to about 95 VAC 15 seconds later. I assume that I have a bad element due to no continuity but why is my voltage dropping from 240 to 95 after 15 seconds ? Thanks in advance for any help...
Answer Hi Mike. If you measured the element ohms and find that the element is open or even shorted against it own base mount ground then just as soon as has full power then it sows a 50% or better drop because you are loosing one side of the power. Start at the terminal block on the unit. Make sure with the breaker off that you have full 240 vac to the outer 2-terminals and 120 volts from the middle terminal (neutral) to each outer terminal leg L-1 and L-2 as well . If not then you have a supply issue with possibly a bad terminal block post part #  or house outlet voltage issue. Remember as soon as you apply voltage ( & amperage ) to a cold element it may suddenly draw current needed until the weakest part of the element reopens and then you lose voltage. One side of the power will come directly from the terminal block to each one side of the bake or broil element. Then when you command the bake or broil function, the corresponding clock relay closes and gives you the other half of the 240 volt ( 120 volts) to the element. Follow the wire going to the element from the terminal block and make sure you have 120 volts to it and to the neutral terminal under live conditions. Remove power. Then unplug the other wire to the bake element coming from the clock relay. with the wire disconnected insert the red meter lead and then place the black lead to the ground or the neutral with the power applied and the command given. If you have less then 118 -122 volts then consider replace the clock assy. because the relay contacts may not be passing the correct voltage either. Please double check the correct model # so we can assist you further with correct part #'s. Thank You.
