If you are using the control panel to operate the oven try it in the Manuel mold (open the door under the control board) and set the
t-stat to the cooking temp .if it cooks ok (you have to time it your self )the probe will be the problem,if it over heats i would think
you have stuck contactor

Re: Lang Oven EHS-PP
WB, Your thermostat is shot and must be replaced. The most difficult part of this job is locating one to replace it with.
Have the complete Model and Serial number handy...
First, try locally. Call a local Commercial Kitchen repair/parts house. Surely theres one nearby, they work on all McDonalds, Wendy's, Restaraunts, etc... cooking equipment.
Second, contact the manufacturer;
Star Manufacturing International, Inc.
10 Sunnen Drive
St. Louis, MO 63143-3800
After you have it, SHUT OFF THE POWER AT THE BREAKER!!! Now try to turn the unit on to VERIFY you have no power. Then remove the t'stat knob. Now remove the screws holding the control panel in place. Tilt the control panel out toward you. Now you can see the t'stat and see how the sensor bulb is routed. (HINT: Take a piece of paper and draw the back side of the t'stat's wire connection locations and wire colors/numbers, BEFORE removing anything.) Remove the wires and the t'stat and route/wire the new one the same way.
Another tip; Be extremely careful with the sensor bulbs capillary tube (the small tube connecting the bulb to the t'stat). NO 90 DEGREE BENDS ALLOWED! It is a hollow tube, if it's piched/kinked you can throw it in the trash and buy yourself a new one. (It came packaged as a coil for a reason) As you uncoil it, go slow and easy.

Don't worry my wife does the same thing. Not sure if your talking about the range top or the baking potion. We'll assume the baking area. If your using cheap bakeware that could be part of the problem try using a different cake or loaf pan of heavy construction. Also you may try reducing your temp in 25 degree increments to see if your oven runs hot. Example buy 3 cheap frozen pizzas and if they say value at 400 try 375 , 350, and 325. If one of those temps gives the desired result assist accordingly and consider contracting Bosch customer service to inquire about how to fix thermostat errors.hope that helps I didn't have much to work with.
Here a list of Whirpool oven fault codes. The codes had been collected from different service manuals. This was a memo that I wrote for my own use. I think this can be useful to owners and technicians.
WHIRLPOOL - most models Range/Stove and Oven Fault Codes, Common error codes.
F1 - Analog control board Failure Disconnect for one minute - if error comes back, replace control board F1 - Shorted control keypad Replace keypad F3 - Oven temperature sensor open Replace oven temperature probe F2 - Oven temperature sensor shorted Replace oven temperature probe F3 - Oven too hot Replace oven temperature probe F3 - Clean temperature too hot Replace oven probe F5 - Door latch switch fault Test and replace the door switch.
Whirlpool with 4 Digit Failure Code:
F1 - E1 - Electronic control (flip flop) Replace control board F2 - E0 - Shorted control keypad Replace keypad F3 - E0 - Oven temperature probe open Replace temperature probe F3 - E1 - Oven temperature probe shorted Replace temperature probe F3 - E2 - Oven temp too high Replace temperature probe F3 - E3 - Clean temp too hot Replace temp. probe F5 - E0 - Check door latch F5 - E1 - Check door latch Replace switch if defective
WHIRLPOOL Polara models 5 digit codes:
F1 F0 - EEPROM communication error Replace ERC F1 E1 - EEPROM checksum error Replace ERC F1 E2:7 - UL A/D errors Replace ERC F1 E4:2 - Model ID error Reinsert keytail. F1 E6:0 - Latch signal mismatch error Replace ERC F2 E0:4 - Shorted key error Replace keypad assembly F2 E1:3 Keytail unplugged reinsert the keytail F3 E0:5 Top oven sensor open Test and replace top probe. F3 E1:6 Top oven shorted Test and replace temp probe F3 E2:9 Bake range over temperature Test and replace temp probe F3 E3:8 Clean range over temperature Test and replace temp probe. F3 E4:10 Bottom oven sensor open Test and replace temp probe F3 E:15 Bottom oven sensor shorted Test and replace temp probe F5 E0:14 Door switch errot Test and eventually replace door lock switch F5 E1:16 Door latch not operating Test and eventually replace door latch F8 E0:17 Refrigeration error Test the cooling module. PF Power failure - Does not indicate a fault. PF occurs when power is disconnected.
WHIRLPOOL Models SF3, 30'' and 24"
F2 - Oven temperature above specifications Check 8-pin connector from temp. probe to Electronic Oven Control F3 - Open oven temperature probe failure Check wiring, replace oven probe if necessary F4 - Shorted oven temperature sensor failure Check wiring harness, replace oven temperature probe if necessary F5 - Push button stuck or faulty Check for binding of pushbuttons and control panel glass. If OK, replace touch panel F6 - Electronic control logic error (timing) Replace Electronic Range Control (ERC) F7 - Electronic control logic error (lock motor) Replace ERC. F8 - Electronic control logic error Replace ERC.
That code refers to the oven temperature sensor sensing a too hot oven. I suspect what you did to quite the cleaning cycle should help once the temperature cools down the door should open. I am a little confused, did you set the oven to clean while your cooking, or did it do this on its own, or was it preset and yopu forgot it was set to clean? Your temp sensor may be going bad if it just detected a too hot oven while your cooking. If it started cleaning then it may have gotten too hot and this is the safety device to prevent it from overheating. it sounds like it is trying to self clean, its essential that you find the error code sheet, stuck in the stove or oven cabinet somewhere, also check your range settings so that it is not set to auto clean.
make sure that the bottom is actually coming on andnot just the broil portion... fi it is indeed coming on then sounds like the thermostat is bad on unit... usually is a temp probe that comes into back of oven or in the rear side ranging from 2 inches to 4 inches in length..the temp prob will go back to the control ...i would start there...good luck to you
not that familiar with the brand but in other case have fourn the board to be engaging the self clean. not a good sign. and for this model i would think very costly. wishful thinking says the oven temp sensor but i think you have a fauly board. get the same thing with alot of frigidaire ranges.
What are using to measure temp ? Are you using a grocery store bi-metal or professional thermal probe ? and further to that, how long are you waiting to check temp. after range "beeps" or announces preheat complete ? The bi-metal type thermometers do take several minutes longer to reach actual temp as opposed to the ranges temp. probe. Does this unit have the "hidden" bake element ? That sounds like a huge temp difference. These units do require an additional 10mins of wait time after announcing ("BEEP") the preheat is complete (check your manual, it should confirm this) Elements don't go "bad" it either comes on (amp draw) or it doesn't.
If your model # is ECOH-AP208DR, Electric Half Size Computerized Convection oven, the timer is as follows: 2J-30800-05 Timer Elec. 1hr 24V. Please check the time range of 1 hour and voltage on old timer be insure this is correct.
I believe the fan is supposed to rotate one way, then stop and spin the other way, ie. clockwise, then counter clockwise. Did the service guys check this? what service company did you use? You probably already know this but make sure the sides of the pan are NOT touching any of the sides of the oven. I work for a service company myself and I have to say if I got this call and neither of those two things solved it, I would be stumped!
