Shannon I have a very old Jenn Air Cooktop with a downdraft in the middle of it and a cartridge that holds 2 burners each. One Cartridge on the Left, Downdraft in the middle and Cartridge with 2 burners on the right. I am not sure of the model # since the lable in the downdraft is unreadable. The wires of the Burners in the right cartridge were all burnt and were rewired with new wiring. Now the right front burner knob is turning both burners on at the same time but the back burner knob is not turning on any burner. What would cause one burner switch to turn both of the burners on at the same time? The label on the Downdraft Plenum says 2375/90. I am thinking this cootop is 2375ERS. Would a bad infinite switch cause this issue? The infinite switch says on it 240-112 7036F 7W 74h 15A 240 VAC The back of the cartridge that the burners sit in says 87818 & 87847 To be used only with Jenn Air Range Model # 3800-3875-3890ERS 3350 Watt 240 Volts. Please help.
Answer Shannon, With this issue it sounds more likely that when the wiring was replaced something got wired incorrectly causing the one burner switch to turn both burners on like they are both connected to the same switch and nothing being connected to the other switch. Unfortunately due to the age of the unit we would not have any wiring information available to determine this. Read More... Answered by AppliancePartsPros.com | Wednesday, November 23, 2016
