Question about Kenmore 62702 Microwave Oven

1 Answer

Steams My Kenmore Microwave heats just fine, but when I open the door, regardless of what I have cooked inside, a billow of steam comes pouring out the door. I leave the door open for a few minutes until the steam disappates. Is there something wrong with it or is it safe to continue to use it?

Re: Steams

It could be a problem with your cooling fan or hood fan not venting the cavity enough.

To help you most effectively, it's better to post your full actual model number. But I'll give you the general info for now.

If this is a countertop model, you should feel strong air flow coming out from the back.

If it's an over the range model, you should hear the internal fan blowing when you hit Start and see the steam moving around while it's heating.

If the fan is not blowing and air is not blowing or if the next system is not working or blocked, you will get more steam than usual and the magnetron will likely end up being damaged.

Some steam buildup inside is normal, but not too much. It's kind of subjective, but it's dependent to a lagre degree on that air flow.

Most newer models don't have any gaskets to worry about, but older models may have deteriorated gaskets which limit the air flow.

Please write back with more details if you need further help.

We're happy to help and we appreciate your thoughtful rating of our answer once we pose a final solution.

My microwave shuts off, black no power when ever I cook tv dinners, potatoes etc. after 2.5 or 3 minutes. After 10 minutes or so, power comes back on and it displays PF. lots of steam inside after.

Hi Kerry,
"PF" is power falure if you didn't aready know this. It sounds to me like the coolig fan might be running slow or there is blocked or restricted air flow through the unit. This cooling fan is only for the HV transformer and magnetron. Sometimes you may get air flow around the door but this is incidental. The PF tells me that the power is being interrupted either at the power source (wall outlet or circuit breaker) or the magnetron TCO is cutting out. It also could be a bad magnetron running too hot. As far as the steam goes, I usually just leave the door open on my microwave for 10 or 15 minutes to let the condensation evaporate.

Was it just the exhaust fan that came on? If so this is normal when cooking on the stove for long period of time without the fan running. The heat builds up under the microwave and eventually activates the fan.

I have a GE microwave with the message sensor error

On GE models, "SENSOR ERROR" appears on the display when:
  • Using the sensor feature, the door was opened before steam could be detected. Do not open the door until stream is sensed and time is shown counting down on the display.
  • Steam was not detected in the macimum amount of time. Use Time Cook to heat for more time.

Microwave runs but does not heat food either with sensor or manual timing. Occasionall will displasy 'SENSOR ERROR'. Have closed door and pressed CLEAR/OFF per manual instructions, but still does not...

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for maybe an hour.

Then let us know if the hard reset does not fix it.

INFO: On GE models, "SENSOR ERROR" appears on the display when:
  • Using the sensor feature, the door was opened before steam could be detected. Do not open the door until stream is sensed and time is shown counting down on the display.
  • Steam was not detected in the maximum amount of time. Use Time Cook to heat for more time.
If the reset didn't fix it:

When you hit Start to cook, do the inside light and turntable come on?

Any unusual noises?

Is it louder or quieter than usual?

Do you have the model number?

These answers will help me judge whether it's in the high voltage section (magnetron, transformer, or diode) or the control section (door switch or control board relay or connection).

Door Window steams up on Microwave

Is the internal cooling fan running? You should feel air flow from the grille in the front or back (as the case may be).

If it's just steaming up the inner face of the door, that's fairly normal, but if the steam is appearing inside the layers of the door, that is not normal.

Since it's new and you've got a warranty, I would call Emerson.

Microwave turns on, but no heat or turntable movement

Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure, but it may also be a broken switch mount. I have a text file called "doorsw.txt" which helps in diagnosing and repairing door switch problems, and a file called "safety.txt" which is of vital importance. It is at our site, which is linked at our listing here on FixYa: You can find helpful exploded view diagrams and order parts by entering your base model number (without the suffix) here: or at
