Panasonic Microwave OVEN, Model # NN-T785SF Whenever the start button is depressed,you would hear a click,the oven light comes on and the fan also. In about two(2) or three(3) seconds afterwards you would hear another click,the oven light and the fan would gone/turnoff. There is no heat - none at all!!! What is wrong here?.Need some advice Thanks in advance Th timer is normally set and countdown but it does not complete its time period when it clicks off. For e.g. If i set a time period of 3 seconds it would count down to 2 seconds then turn off,if i set a time period for 1 minute it would turn of within 5 seconds and if i set a time period for 2 minutes, within 5 seconds it turned off. This type of behavior is just unusual or improper for a microwave oven. Thanks for the reply
