What will be the good replacement for part 7403P438-60 Fan switch for jenn air cooktops?
Answer Hello Bo! To verify the correct manufacturer replacement we'll need the appliance serial number. Please obtain this information and repost for further assistance. Thank you.
The fan and burner lights stopped working. I pulled the switch and test the resistance. It was infinite in all positions. I powered the fan motor independently and the motor works fine. I ordered and replaced the old fan switch. It still doesn't work. What else could be the issue. I noticed the old switch says it is 120V. There is no AC power to the switch. Is there a fuse link in this controls?
Answer Hi Don. Your wiring diagram is supplied w/ the unit under the base plenum. Use it along w/ our suggestions to make sure your wiring diagram is the same. The fan sw. gets its power from the terminal block colored brown that connects to the lt side elements or the grill. Check there for the lost 120 vac feed. Either a bad connection or burnt wire. Remove power and be safe. There are 2 terminal blocks(the other one black). Check at the unit terminal block for proper 240 at the outer 2 terminals and each outer to the center terminal(neutral) for proper 120 vac also. Maybe you lost the feed at one of these legs. Check the terminal block for tight clean connections. Check the breaker to see if it is Half /tripped. Let us know how we can help. Thank You.
Which wires hook up where on the switch? No schematic provided.....
Answer CP, There should be two(2) terminals on the new switch, and wiring is not polarity sensitive, so location of the wires is pretty basic. Either terminal should have a single black wire(L1) from the infinite switches/ power cord(thicker black wire). The other terminal will have three(3) wires attached to it, the two blue wires, that are routed to the receptacle in the cooking bays, and the thinner black wire that is routed down to the vent motor harness. Thanks and Good Luck
