Service Code F-3 - Magic Chef Ovens

Question edited for clarity and all the typos.

All questions need 'make model (what it is)' as first 3 words.

Generic advice on a generic F7 Oven Error code.

F7 error code can be a result of a faulty wire harness (short-circuit), defective heating elements or oven sensor. A qualified service technician will need to have a look, determine faulty part then replace or repair it.

..

So I found the service manual for this model.

https://www.rational-online.com/media/downloads/en-gb/manuals/rational-original-operation-manual-cmp-en-gb.pdf

The list of codes is on page 105. Code E34 is simply listed as contact customer service. Which is not really all that helpful in diagnosing the problem. Have you tried to reset the oven? Disconnect the power cord for 2-3 minutes and trying again? If this doesn't work, given the general code, you should call the customer service number in the manual.
Hope this helps.

I found this on line don't know if it will help but it might send you in the right direction for testing to determine if it's worth repairing-- sorry
Shortly after a series of power failures I started receiving this error code. Looked up it online and did some extensive research. Everything pointed to a faulty sensor so I purchased a new sensor and installed it today. It didnt help, and testing my old sensor I determined it was also working. In the service manual it stated to do the following corrective action for the F3 - E0/E1/E2/E3 error codes:

Quote: 1. Measure sensor value (between connector pins) between 1000 ? @ 32° F and 2697 ? @ 900° F (room temperature approx. = 1080 ? ). If measurement does not correlate to real temperature, disconnect power, replace sensor and refer to steps 3-5. Also measure from sensor connector to sensor casing for possible short.

2. Trace wires and connectors to sensor, from control, then from sensor back to control. If all connections made and no wire damage, refer to step 3.

3. Disconnect power for longer than 30 seconds

4. Re-apply power and press BAKE and START/ENTER. Observe for longer than 1 minute.

5. If failure remains, disconnect power, replace control, then go back to step 4. I also tested the resistance of the sensors control panel wire harness connector and they are correct. Next step outlined in the service manual is to replace the control board. Sears has the control panel in stock for $177.47. This to me is not worth it over the cost of a whole new oven. Are there any fuses or anything else that could easily or cheaply be replaced before throwing out the oven. Thankyou very much in advance for your time!

Here's the info from the service manual:

"Fault Code: F9

motor switch failure.
2. Control software failure, or component
failure (relay stuck).
3. Wiring Problem.

Suggested Corrective Action:
1. Press CLEAR key.
2. If CLEAR key does not eliminate problem, turn off power for
30 seconds, then turn on power.
3. Check wiring of Lock Motor, and Lock Switch A and Door
Switch circuits.
4. Unplug P4, apply power (L1) directly to the Lock Motor, if the
motor does not rotate, replace Lock Motor Assembly. Plug
P4.
5. Check Lock Switch A for proper operation (do they open and
close, check with ohmmeter). The Lock Motor may be
powered as in above step to open and close Lock Switch. If
the Lock Switch is defective, replace Motor Lock Assembly.

HI The range timer is usually located in the control panel on top of the range. If you suspect the timer is faulty, don't try to fix it yourself. Remove it and take it to a professional service person for testing. Here's how to remove the timer:

Step 1: Remove the back service panel to the control panel and release the spring clips that hold it in position, or remove the retaining screws.

Step 2: Push the timer forward to release it.

Step 3: Remove the electrical lead wires from the timer housing. If, when disassembling the timer, you notice that the electrical wire terminals look burned, remove these leads and buff the leads and the terminal points with fine steel wool. Burned and/or dirty terminals can cause the timer to malfunction, but a good cleaning can solve this problem.

Step 4: Replace the old timer or install a new one of the same size and type, if this is necessary. Connect the new timer the same way the old one was connected.
