CVE4270B-C Jenn-Air Cooktop - Instructions

throw breaker, unbolt switch, unplug leads, rerplace switch, bolt in place, reattach leads, turn breaker back on

I first turned off the power to the range. The switch was housed inside a control panel in the front center part of the range. Two screws were removed and the housing was lifted forward and then off The switch was held in place by metal friction washers. Those were removed by a screwdriver and then the switch slide off the posts that they were attached to. The switch had two wires and I simply replaced the wires onto the new switch and placed the switch back onto the posts. The friction washers were pressed back over the posts to hold the switch in place and then the housing was screwed back into place.

Looked up schematic. Removed 3 screws holding cover. after I shut power off of course. Took off knob. Oriented new control to the one on panel. Disconnected each wire one at at time and immediately attached it to the new control for each wire. Removed screws holding old control and inserted and screwed to the new control and put the knob back on. Put the cover back on. Worked fine. Probably should replace the others as they don't turn as easily as the new one. Probably will spray some contact cleaner which will give me a few more years.

Turned off power to range top. Two screws to lift the control area. One snap on was burned off.
Removed tab from inside same. Used nut driver to remove switch. Taped wires and restored control area. Power back on. Went to computer and got website for Partselect. Found description of part got me to several choices. The range is 25 years old. Selected a switch that seemed close. It arrived in two days. Redid the same steps. Some file and drill work required to make switch fit. Screwed switch in place. Untaped snap connectors and attached to switch. Checked for function and and restored control area.

Opened the back of the cooktop and found upper right element control switch burned. I removed the retaining screws and wires and spent two weeks chasing the switch at a local dealer. Found exactly what I needed at PartSelect.com and paid less even with shipping than at the local. Installed the switch with original screws and presto!! it worked.

Remove 4 screws that holds down panel;removed dial;removed screw that held switch to panel. Took off wire one at a time ann put on corresponding lug. Repeated above in reverse.

We unplugged the range from the wall first so as not to get electrocuted. We removed the face of the control panel by removing the screws and 2 hex nuts underneath that hold it in place, and removed the trim. Then we disconnected the malfunctioning control switch, taking note of what order the wires go in. Hooked the new switch up and popped it through the face of the control panel. We then put the trim back, and reattached the control panel with the screws. Very easy!!

First I located the proper breaker in my electrical panel to turn off the power to the cook top. Then I removed the two screws that hold the housing of the burner knobs and fan switch and lifted it up as much as the attached wires would allow me. To replace the Infinity Control Switch I removed the two "star" head screws from top of housing (under knob) which allowed me to pull the switch off of housing. I pulled off each wire, one at a time, and attached them to the identical place on the new control switch. With all the wires reattached I installed new switch into hole and replaced the 2 screws. To replace the fan switch I removed the 2 nuts on back of housing which allowed me to drop down the switch, swap the wires onto the new switch and place it back onto the bolt posts and reattach the nuts. Finally I turned the breaker back on and tested both new parts to make sure the problems had been corrected. Cook top works perfectly now.

Un screwed the two screws in the downdraft section enough to release the unit that holds the surface burner controls.Then removed the control nob, unscrewed the two screws that holds the switch in the unit, removed the wires, making sure the color of the wires were placed on the same contact point. Put it back together and it worked
fine.Of course I did shut off the power before starting any of the above

removed two screws under fan cover at end of stove knobs. raised panel with knobs up and removed two nuts that held fan switch housing. installed new switch and moved power connections to new fan. (note: Killed power to range top prior to any repair action)

Changed out surface burner switch.Unscrewed two screws, changed plug onto new switch.Don't forget to turn off power!

Pulled the old one out & inserted the new one. Less than five minutes.

Replaced one of the four burner control switches on my Jennair cooktop. One of the tricks I use to prevent mistakes is putting the new switch along side the existing one and swap one connector at a time over to the new switch preventing any confusion and negating any need to mark the wires. This differs from your video assistant who disconnected all the wires at once.

We replaced the burner grates, knobs, air filter and burner pan. Looks as good as new!
