Microwave oven Amana

Is there a repair manual for Amana Model No. RR-9TA, MFG. No. P73559-3M, Serial No. EC 54553906 ???
Thank you!!!

Touch screen went out. Unit made short tone as if unplugged or power outage. Very faint P shows in display. Oven light operates. Oven operates if **push button On switch is held in, but no heating occurs.
After unplugged then re-plugged in and about a 1/2 hour then display will be active again and oven functions for several heating cycles until outage re-occurs.

Hi,

I could not locate a service manual for that model.
You may have a bad connection on the control board.
