Panasonic microwave ovens touch pad is not functioning in winters. But works well on a warm day. Do I need to clean out something specific?

The pads actually share some of the same lines inside the touch pad. There are silver oxide traces inside there. If a trace inside breaks, it depends on which trace breaks as to what pads dont work. If a trace that is common to say pads 1,3,5,7 you would lose function of those pads. 1.....2.....3.....4......5....... it is sort of set up like that inside wher eone connects to another and so on. So lets say a line between 2 and 3 breaks then you would lose pads 3, 4, 5 and any others on that same line. Will have to replace touch pad, cannot repair.

This is due to fault in the touch pad or the front control unit. There is dirt or moisture which triggers the start to function on the processor board. You need to remove the front panel and remove the touch pad /controls, try and dry using a dryer to warm. If there is no result the pads must be replaced. Also check for clogging of insects within the board which can trigger the start function or malfunction. remove and clean the board.

F 11 code. it is a touch pad error.
If you just cleaned the control panel it may have water in the panel causing a key to stick.
If after a day or 2 it hasn't dried out - then you will need to replace the touch pad.

HI. this is a code that represents a failed key pad or touch pad membrane board. replacing this failed touch pad will fix this issue. This touch pad board is separate from the actual control board.

this feature allows you to program your oven to begin cooking automatically at a designated time of day. Simply touch Custom Help pad. Touch the number 3. Enter the start time. Touch Clock pad. Enter cooking program. Touch Start/Touch On pad.

HI, the key pad or, touch pad is defective. you will need to replace it asap if possible.
