Exterior of oven , top and both sides gets very hot to touch, when cooking +- 10 minutes or more the last couple of days; no Error ( E41/42/45 or 47 are being displayed. Fan is normal, functions: OK


There could be food or oil buildup around the door frame which will absorb some of the radiant and microwave energy whilst cooking. Give it all a good clean and see if that helps. If everything else is working properly, it may be a problem with the cooling fan. Microwave ovens have a "stirrer fan" inside the roof or rear of the cooking area to disperse the microwaves and some convection / microwave ovens also have a cooling fan which assists in dissipating heat within the cabinet.

GE microwave not heating, sensor error.


first suspect is the inverter board (power) and magnatron a distant second----in either case the part involved unless an expensive unit is pricey.

Emerson microwave not working 900 watts


The Emerson MW8999SB 0.9 cu. ft. 900 watt Microwave Oven is relatively compact, and certainly inexpensive, but doesn't skimp on functionality. We were surprised at all the options you get with this little microwave. It's only 20 inches wide, 11.3 inches high and 16.1 inches deep yet. The interior can still accommodate a regular size dinner plate or small (10-inch-square or round) casserole. Plus, there are 10 power levels, eight one-touch function buttons, six Express Cook settings, timed and automatic defrost options, and a rotating glass turntable to circulate the food for more even cooking.

We were very pleased with the performance of the Emerson MW8999SB. It did a fine job heating water for tea, cooking a couple of baked potatoes, reheating leftovers and steaming fresh vegetables. Even the automatic defrost proved surprisingly efficient, letting you enter the weight of the item(s) to be defrosted (4-100 ounces) for easy operation. Chicken breasts were almost fully defrosted after one cycle. We needed to stop and separate the food pieces to finish the defrost cycle.

The unit is styled mainly in black but has stainless steel trim around the door and control panel. The smooth touchpad control panel is attractive and easy to wipe clean. We loved the one-touch Express Cook buttons, which let you activate the unit at 100 percent power for 1-6 minutes, by pressing the corresponding number pad. We also appreciated extra touches such as the Start/+30 sec. button, which can be used to start the oven or add an extra 30 seconds each time it is depressed.

It's hard to go wrong when the functions are so simple. The only tricky part was identifying certain codes used on the display screen. When changing the power level, for instance, PL10 is displayed on the screen. Pressing the button additional times lets you toggle through the different levels. Likewise, the Auto Cook settings may need to be pressed multiple times to obtain the correct weight or portion for the food being cooked.

We were amazed that a machine costing so little also offered two-stage cooking, which lets you start cooking (or defrosting) on one setting and finish on another. All in all, the Emerson MW8999SB is an excellent value.


Pros: Touchpad controls, eight one-touch function buttons, six Express Cook settings, two-stage coking option
Cons: Limited interior capacity can only accommodate dishes up to 10 inches, no sensor

What does F2 mean?


The error code F2 on your GE microwave indicates "Shorted thermal sensor", this condition will occur if a shorted thermal sensor is detected continuously over 5 seconds on convection, combination or roast cooking.
. It takes a minimum of 5 minutes of convection run time before this code will be
displayed. More information on this error code, as well as other error codes, can be found at
http://www.applianceaid.com/micro_faultcodes.html#gemicro

Best of Luck with your microwave.

I wouldn't worry about the sensor error right away.

Sometimes that's just caused when the door is opened before steam could be detected or steam was not detected in the maximum amount of time.

Once it's all working again, if you still get the error regularly, it may be a bad humidity sensor.

If the internal cooling fan IS running when you try to cook AND the oven is not heating, it's probably a failed secondary interlock relay on the control circuit board.

If the internal cooling fan is NOT running when you try to cook AND it's not heating, the bottom door switch is probably the culprit.

Here's is a file on checking and replacing door switches.

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are working.

Listen to that very carefully, and listen to yours to see if the cooling fan is working.

When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually.

I'm instead talking about the internal fan which comes on automatically whenever you microwave.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Let me know if I can help you further.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Kenmore Gas Range model # 362.75491990 F3 error Oven will not hold temp - error message displays and beeps I Replaced the oven temp sensor same issue Is the control panel bad?


Hi,

Many models of the GE microwave have sensors that can detect humidity from the foods you are cooking. This allows the microwave to make adjustments to the power levels used to cook your food. If "Sensor Error" appears, you should either press "Clear" to cancel the mode or leave the food in the appliance longer to give the microwave more time to detect the food.

Press "Time Cook" to manually enter the time if you receive an error message when trying to use the "Sensor Reheat" mode of your GE microwave. The error message may be caused by the food item being too large or too small to detect.

these are some other code error that will help you in case of next time.

  1. Step 1 Press "Off/Cancel" (or "Cancel/Off" depending on your model) to clear the error code. Note the code if it reappears.
  2. Step 2 Replace the touchpad if the code displayed is "F0," "F7" or "F10." A function key is stuck or shorted.
  3. Step 3 Replace the touchpad or the clock (ERC) if the code "F1" is displayed. Disconnect the ribbon connector to the touchpad. If no code is displayed after an hour, replace the touchpad. If the code displays again, replace the clock.
  4. Step 4 Replace the oven temperature sensor if "F2," "F3" or "F4" is displayed. "F2" indicates the oven temperature is too hot and the oven temperature sensor is suspect. "F3" or "F4" indicates the oven temperature sensor or shorted or open.
  5. Step 5 Replace the ERC if "F5," F6" or "F8" is displayed. The ERC is the main control unit. "F5," F6" and "F8 are codes that indicate problems in the ERC functions.
  6. Step 6 Inspect the door-lock assembly and circuit if "F9" is displayed. The door must lock when the oven is in use. If the lock mechanism is not functioning or if the detection circuit is malfunctioning, the stove will display "F9."


jQuery('.article ol .image').each(function(i,e){ var $this = jQuery(this); $this.find('img').error(function(){ jQuery(this).remove(); $this.remove(); }); }); NOTE:


"F3" codes mean your oven temperature sensor has failed or shorted out. The only thing you can do is to replace the sensor.

Take care.
