Jenn-Air JGR8875QDS Gas Kitchen Range - Answered Questions & Fixed issues

Hello. The pictures I've attached are the best I can do for the schematic of your unit. The service manual has been poorly copied into a computer file and the schematic is hard to decipher even when directly looking at it! I hope I helped you!

Hello,

The F1 error code means that the computer thinks a button on the touchpad is stuck. Sometimes this can be resolved by making sure the touchpad connector fits tight into the control board. The F1 code can be cleared by pushing CANCEL/OFF. If it returns the touchpad needs to be replaced, GENE

I was able to find online some metal knobs that MIGHT work, but the prices ranged from $30 to 60 EACH, and I needed 5 - too costly for me!
The following 3 plastic knobs will work on your Jenn Air range, model JGR8875QDS. By "work" I mean they will fit your burner controls, operate the burners just like the factory knobs, and the markings on the knobs for "Off" "Lite" and "Hi" will be in the correct positions, similar to the factory knobs. (Exception: The last knob listed has markings somewhat different than the Jenn Air knobs.)

The following knobs do NOT look like your factory knobs - all three are made from black plastic rather than the (fake) silver metal look of the (plastic) OEM knobs. What I cannot tell you is if the following knobs will be more durable than the factory knobs - but then it's hard to imagine how they could be much worse.

-------- Burner control knobs known to work on the Jenn Air JGR8875QDS gas range --------

1. Whirlpool part number 74008850, made for some Amana gas ranges, will fit the Jenn Air. RepairClinic.com calls it part #1035119, and PartsSelect.com calls Item #PS2086316; it sells for $6-7 (USD). You can see a photo by entering the appropriate part number in the search box of either of the two websites mentioned above. The Amana knob is about a quarter-inch larger in diameter than the OEM knobs, but that does not cause any problems. Of the several knobs I tried this is the only one that tells me what it's made from - "PBT" - or polybutylene terephtalate, a thermoplastic which has a melting point of 430 degrees F and a maximum utilization temperature of 330 F.

2. Whirlpool part number 74009094, made for some Maytag gas ranges will also fit the Jenn Air. RepairClinic.com calls it #1035342, and PartsSelect.com calls it #PS2086544. It sells for about $9 on both sites. You can see it here: 
www.repairclinic.com/Appliance-Parts?s=t-74009094-%3d%3d
Like the Amana knob, the Maytag knob is about a quarter-inch larger than the OEM Jenn Air knob.

3. A third knob worth considering is available from AmericanStoveParts.com for $7 each. The front of the knob looks much like their OEM Replica Burner Knob 1104-B (but don't order #1104-B - it won't fit). The knob that will fit the Jenn Air is AmericanStoveParts #1214-025-B. You will have to order it by phone or email because it is not shown on their website. (As of October 2009, none of the knobs shown on AmericanStoveParts.com will fit the Jenn Air.) 

Notice the markings on the 1214-025-B are not quite like the Jenn Air markings, with the "HI" and the "LITE" positions being reversed. Also, the 1214-025-B knob I received did not have the white dot at the "OFF" position nor the white ring around the periphery as shown in the photo of the 1104B knob. The total diameter of the the 1214-025-B is 2" - the same as the factory Jenn Air knobs.

While I don't think the front of 1214-025-B looks quite as nice as the Amana or Maytag knobs, the back of the knob appears to be much more robust than on the others. The extra plastic MAY make this one more durable.

I have installed the Amana knobs (#1), and I will report back if it proves unsatisfactory.

nope new are plastic to look like metal

Any appliance store should be able to get those parts for you. If not try sears/lowes etc or look for a marcone/apwagner near you

Try unplugging the oven from the electrical power. May release the lock, which is held in place by a tiny micro switch. If not and while the electric is still off or the oven is unplugged, use a bright light flashlight to look through the slot where the lock is in the oven, not in the door.

You may be able to use a thin blade screwdriver to move the lock to the release position. Check the angle of the lever. A slightly bent lever handle also can cause this type of condition.

If all else fails, remove the access panel on the front of the oven to access the locking device and release it. May have to disconnect the wires to the lock which will allow door to function but not during any self cleaning modes.

Hi,

There are many places to order them from. The part number you need is 74009148

I would recommend you get them from Jenn Air directly to make sure they match. There are several other places I will list a couple here.

You've pretty much diagnosed the most common cause of the symptoms you are describing. There is a small button under each control feature on the display overlay. You can attemtpt to remove the circuit board and clean the buttons to see if this will restore any of them to full operation. The following link explains step-by-step how to remove and replace the control panel on most kitchen ranges:

http://www.fixya.com/support/r3727366-replacing_control_kitchen_range

Remove the control board from the range and clean all the button tabs with some isopropyl alcohol. If cleaning the circuit board does not work for you, replace the control board.

NOTE: Make sure you UNPLUG the range prior to servicing anything inside the operator control panel.

You can order replacement parts from any of the following websites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

All these sites offer great service with competitive pricing, so shop and compare. The first three sites on the list also include helpful exploded view diagrams of your appliance to help with locating and properly identifying the parts you need.

NOTE: If the model number is correct, the overlay is the entire control panel cover. This has to be ordered separately and costs almost as much as the control board itself. I would recommend you reuse your current overlay if in good shape. The part number for a replacement control board is 74009154.

If you have any questions, or if your model number differs from the one you listed this question under, please post back and let me know. I hope this helps you.

Hello,
The problem is the igniotr is taking very long to heat up...
Replace the ignitor and you will be okay again.

Here is a tip that I wrote about this problem...

Hello - Most likely failed lower burner ignitor. Tests good if above 4ohms. Part is 40$. Can give replacement instructions if needed. Let me know if this helps. Thanks. -ED

In less than 6 years of normal use, 4 burner control knobs on my Jenn-Air free standing gas range, Model JGR8875QDS, have either broken or melted.
 
If you want to continue to buy Jenn Air knobs, no problem - several suppliers will be glad to provide them for  $10-15, each (USD). Whirlpool's part number for the factory Jenn Air knobs is 74009148, and you can get them from repairclinic.com (#1035396), or PartsSelect.com (#PS2086597).

If, however, you want to try a different set of knobs, hoping to find some that are less prone to break or melt, then it gets a lot more complicated.

Jenn Air/Whirlpool will be no help; they will tell you the only knob that will work is the Jenn Air OEM knob. Parts suppliers won't help you either - no specifications or interchangeability data exists - and they are unable or unwilling to take measurements.

I can tell you the following 3 knobs will work on your Jenn Air range, model JGR8875QDS. By "work" I mean they will fit your burner controls, operate the burners just like the factory knobs, and the markings on the knobs for "Off" "Lite" and "Hi" will be in the correct positions, similar to the factory knobs. (Exception: The last knob listed has markings somewhat different than the Jenn Air knobs.)

you probably need anew oven ignitor

first try a Hard reset...
find the house breaker panel find the oven breaker should be a double 40 or 50 on it .. turn it off for 30 sec than back on....

let me know for it help if NOT please let me know and I will be glad to do more in depth.

there are two ignitors the bake ignitir is probably bad, check that first.

check the outlet, perhaps it's its hokked to a GFI outlet somewhere else in the kitchen and the GFI outlet has tripped

Hi have a nice day!

F8 Analog / Digital problem Replace clock (ERC).
Not hard to replace, just make sure you unplug the appliance first. I can not tell you about a recall, try contacting customer service with that question.

From what your telling me, you have tried all the numbers and only 1,4 and 7 beep when touched. Also, the timer display was set at 0:00 when you started. Also, you followed the manual's instructions first, and looked in the back of your manual in the trouble section, and found no answer. 
Did you timer ever work? If not, you should be able to a free replacement of the control panel module from an authorized Jenn-Air repair company. It may be a good idea to contact Jenn-Air first.
The timer shows only hours and minutes when first started. For example 2:05 is two hours and five minutes. It goes into the seconds mode only during the last minute.

There are several possible reasons why your Jenn-air JGS9900 gas range may not have power:

1. Tripped Circuit Breaker: Check the circuit breaker for the range in your home's electrical panel to see if it has tripped. If it has, reset it.
2. Loose Electrical Connection: Check the power cord connection to the range to make sure it is secure. Also, check the wiring connections behind the range to ensure they are properly connected.
3. Blown Fuse: If your range has a fuse, check to see if it has blown. You may need to replace it.
4. Faulty Control Board: The control board is responsible for supplying power to the range's electronic components. If the control board is faulty, it may need to be replaced.
5. Faulty Igniter: If the burners are not igniting, the igniter may be faulty and need to be replaced.

If none of these solutions work, it may be best to contact a professional technician to diagnose and fix the issue.

There are a few potential issues that could cause the problems you're experiencing with your Jenn-Air broiler. Here are a few things you can try:

1. Make sure the gas supply to the broiler is turned on and that there are no blockages in the gas line.
2. Check the gas valve to make sure it is open and functioning properly.
3. Make sure the gas burners are clean and free of any debris or obstruction.
4. Check the broiler burner for proper ignition. It should ignite within a few seconds of turning on the broiler. If it does not, the burner orifice may be clogged and will need to be cleaned.
5. Check the gas pressure to the broiler. If the gas pressure is too low, it can cause the flames to be low or go out.
6. Make sure the broiler igniter is properly seated and connected.
