CVG4280B Jenn-Air Cooktop - Instructions

The only fan switch available for Jenn-Air was electrically compatible (amps, high/low control) with my 15 year old unit, but the existing mounting plate needed to be modified. The original switch was an undermount and the replacement switch snapped in from the top. This modification required a 1/2" drill bit and a file to square off the edges. Since the plate was cast from soft aluminum, it was fairly easy. Also, one of the spade connections needed to be changed (part supplied). It now looks good and works fine.

1. Turn off power to the cooktop and turn off the gas. This is extremely critical. 2. Remove the knobs and then the covering. Beneath will be the valve part you need to change. 3. Find a way to mark where all the wires go into the piece that sits over the valve (mine was white with a blue ring in the center). You will see four wires going into it. You can photograph it, or you can use tape and a sharpie to write where everything goes on the parts themselves. It is likely that they will become disengaged at some point during your repair, so the step is crucial. 4. Lift off the piece on top of the valve (the valve goes through the blue hole in the center of the white piece). Don't be afraid to give it a tug, as it can be slightly stuck. 5. Find a way to get underneath the large circular plate (mine was gold colored) beneath the valve in order to remove any screws that are holding the valve in place unseen below the surface. 5. Now back above the surface: disconnect the gas valve attached to the valve. 6. Switch out the valve to the new one and reverse these steps to install it. ****7. If you are unable to get beneath the plate where the valve is attached on the underside, no worries. Take the new valve and carefully unscrew the top two screws (need a special tool from a hardware store) and similarly take off the screws on top of the broken valve. Be very careful to remove the top of the old valve slowly enough to see exactly how the inside pieces have to be put together. Essentially, you will find a spring and a small ring with three notches. The small part of the spring goes on the bottom, the larger part of the spring faces upward, and on top of that goes the ring with the three notches aligned in a certain way that's very important so that when you put it back together not only will the valve depress properly but you will be able to change the fire from low to medium to high. Make sure you can depress the valve a little bit, if not you have to readjust the ring until it's in the proper position. 8. Turn on gas and power to be sure it works. 9. Close unit. ***Note: if any of your parts accidentally dropinto the opening, use a magnetized srcrewdriver to retrieve them.

None of the surface burners (two Uni-burners) would light without using a match. I first ordered two replacement PS2089818 top burner spark electrodes. I replace one which was very easy - the electrode just clips into the burner - and I traced the wires down to the back bottom of the stove where I found they plugged into an ignition module. The new electrode didn't help, but since all four burners were out it made sense that the ignition module would be the problem and not the two separate electrodes. So I ordered a new ignition module. It plugged in easily with the terminals well marked like the original. I put the original electrode back in and all four burners now light properly with the desired "tic tic tic" sound with the knobs in the "high/light" position.

blower wheel was caked with dried grease clumps; replaced blower wheel, urethan foam and 3 motor isolators; blower/fan no longer vibrating cooktop.

I removed the burner knobs, unscrewed the 2 screws and removed the cover. I pulled the old switch off the stem and removed the wires. I reconnected the wires to the new switch and pushed it in place on the stem. After checking to make sure the new igniter switch worked, I replaced cover tightened the 2 screws and replaced the knobs. Job done in 5 minutes!

Simply remove old control knobs and replaced with the new ones. I talked to the saleswoman and she was extremely helpful and assured me it was the right part. And it was.

Unplug and pull range away from wall.
Remove metal panel from back of range by using nutdriver to remove 4 screws.
Use phillips scewdriver to remove 2 screws holding old spark module.
Unplug 4 wires from spark module and note placement of wires for reinstall.
Install new module by reversing procedure.
Slide range back against wall and plug in.

Entire process took less than 30 minutes.

NOTE: Spark Module received from partselect.com did not match old part exactly. The screw holes on the new part did not line up with screw holes from old part. I reinstalled new part with just 1 screw. Was told by partselect customer service that the part I received had been substituted and would work fine. It does work but it did not fit correctly.

The 15-year-old Jen-Air stove started smelling really bad. I thought it was a dead animal stuck in the exhaust tube which runs under the floor to the outside. I flushed it out with clorine bleach, but it was still bad. It turned out to the be the grease filter. I washed it every week in the diswasher, but it just was not enough to get it clean enough. Finally, the grease went rancid and smelled really bad. This "repair" took about 30 seconds.

:-) - Just removed the old one and replace with the new one. Nothing to it. Takes 30 seconds.

Extremely easy.
First, I turned powr off to appliance at electric panel (don't trust switches).
Next, I removed the 2 screws that held the panel cover, removed the dials, and removed 2 screws at each one (total eight) - this requrid a hex screw driver bit, which I had in my handy set.
I proceeded to loosen the panel, and disconnect the wires attached to the old switch (this may be tricky - mine came off easy, but did require care as to not to strip the wire from the clamp).
Once the old switch was removed and the plastic housing unscrewed, I attached the new fan assembly, and connected the wires, and reinstalled everything back in the same order.
(This is a good time to clean all the grease and dirt that has collected thru the years-before you put everything back).
Turned the power back on, and everything worked like before.
I figured I saved about 4 hours worth of labor (4x$50=$200 / minimum) plus any inflated part price I would have paid for a $20 part from PartSelect! It felt good!

Turn off power, removed wires from switch, unscrewd lock nuts. Did the reverse to put the new switch with the exception of the the power which should always be turned off first. Took less than 5 min. to install. Wife happy!! which makes me happy.

Removed old burner, replaced with new one, works perfectly! Only one screw to take out and use with new piece.

Turn off the gas supply and unplug the electric supply. Remove the top grates and the burner cartridges. Remove 12 screws around the top cover and loosen the two screws for the fan switch. Pull the fan switch up and out of the way, remove the top cover. With a marking pen, label the four igniter switches and pull them off the gas valves. From underneath, remove the gas line from the pressure regulator, then remove the regulator from the pipe coming from the circular manifold. With a 3/16 socket (1/4 inch drive) or a 3/16 nut driver, remove the four screws that hold the manifold. Then from the top pull the manifold up and out. On the bottom, remove the screw (1/4 inch socket or nut driver) and remove the old gas valve. That's it. Now just put it all back together in reverse order. I used pipe joint compound on the pipe threads. Check for leaks with a soapy water solution. If I had to do this again, it would only take me half the time. I wasn't sure how everything came apart the first time..

unscrewed previous unit, placed new unit and screwed in place.

So very easy!!!! I'm a 70 year old grandmother with a small socket set - and that's all I needed! Removed one small screw, removed old burner, popped new burner in, replaced one screw, and back in business! Placed order, received it in 2 days, fixed burner. So much faster than calling a repairman!
