Re: Lang Oven EHS-PP

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 Phone (314) 781-2777 (800) 264-7827 Fax (800) 264-6666 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.

Re: Lang Oven EHS-PP

This could be simply a bad sensor probe and not the tstat.

Oven burning food

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.

I'm in the middle of cooking dinner and I got a f3 e2 error and the oven do I get my dinner out? My husband is an elevator mechanic so he's handy...we turned off the breaker to quit...

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.

My oven will get a little warm but it will not get hot enough to cook anything.

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

Oven does not reach set temp

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.

hope this helps.

good luck

Lang Platinum series convection oven

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!

Amana Convection oven not controlling temp

I have just checked the baking guide in the manual and have found that it may not be us after all. (Maybe this is why they telll us to read the whole manual. Well, I never have) According to the cooking time for Baking, the range is very extensive. For example, an angel cake at 350 could take from 28-50 minutes, buscuits at 375-400 could take 8-16 minutes, layer cakes at 350-375 could take 25-40 minutes, pound cakes at 325-350 could take 45-70 minutes and fresh pies at 400-450 could take 35-60 minutes. Basically, the baking directions on the box means absolutely nothing to use Amana oven owners. We have no choice but to cook our food or baked goods until they are cooked, whenever that may be. :) Linda
