Samsung microwave model smh7178ste runs, but does not heat. Also E-63 appears on the display

Hi,

Press the "Off/Clear' button to cancel anything on the display, and reset the microwave. This is a soft reset and will simply get you out of any program you have started. Press it when the cooking complete reminder appears on the display.
Perform a hard reset. Pull the plug out of the wall power supply, and wait a moment. Plug the GE microwave back into the wall power supply to reset any anomalies with the microwave's memory. You will need to reset the time of day if you perform a hard reset.
Reset the time of day. Press the "Clock" button, and turn the dial to set the hours. Press the dial to enter. Follow the same procedure for the minutes and a.m. or p.m. Press the "Start" button to start the clock.

It is in the demo mode. To turn off here is what the manual says:

The microwave oven and Timer must be off. Touch and hold Timer Off or the number 3 pad (depending on model) for three to five seconds (depending upon model) until two tones sound and “d” or "Demo" (depending on model) appears on the display. Repeat to turn off and remove “d” or "Demo" icon from the display.

It's almost certainly the primary interlock (top door switch).

See this file for details on checking and replacing door switches.

You can also see the video at our site, which shows you how to access the door switches.

We have the service manual for the model SMH7178STE here, which should be pretty similar. It will also help you with disassembly.

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

E63 is a "T1 Max Time error".

It may mean you have a bad PCB assembly, but I would suggest a hard reset.

Unplug it from the wall outlet for a minute, then plug it back in and try again.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

There is two posibilities, iether the transformer, is not working or the magnatron, there are very expensive, if all the functions are working then there should be an errror code on display

We would need your full model number from the tag on the unit.

Since FixYa is not currently notifying us Experts when Clarification Requests are answered, you will need to post a NEW help request.

In your new post, please include your brand name and the full model number from the tag in or on the unit, your symptoms, as well as the error code you mention.

Hello Hec1152,
I have found the manufacturer contact information for you, but could not find information about the error code. If everything works fine, but the microwave is not heating your food, then the problem is most likely the magnatron or one of it's components, which sadly to say is the most expensive part to replace. Please feel free to contact the manufacturer via phone or live chat to get more details as to what the error code means.

If you would not mind, could you please rate my help. I would greatly appreciate it.

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.

Let us know if the hard reset does not fix it.

There may instead be a stuck relay on the control board, which we repair for customers nationwide with our guaranteed $39.95 service.

Feel free to contact me directly.

Some models are equipped with a sensor that can automatically adjust the oven's heating time based on the amount of steam in the oven.  If your microwave is displaying E1, E4, or E5, there may be an issue with the gas sensor. For an E1 error, press the Cancel button and check on the food.

If the message is either ERROR or E-6, it indicates a mechanical fault.

For all error indications, try unplugging the microwave from the outlet for at least ten minutes and then plug it back in. If the error persists, the microwave may require service. Please use our ASC Locater to find your nearest Authorzied Service Center

Sounds like a problem with a temperature sensor or humidity sensor.
