Hello all. My microwave's clock is acting up and hopefully one of you knowledegable folks here know why. Ok, I can set the clock then use the microwave but when I do, it runs for a second or so then stops and at the same time the clock displays all 0's. Then it's ok to use; keypad works as it should and cooks as usual. The display works fine as in shows the selected cooking time and time remaining. What's causing it to stop cooking after a second or so and at the same time the clock displays all 0's? I know both issues are related but what's gone bad? I figure whatever the bad part is will probably cost not much less then a replacement microwave but want to find out first. Thanks in advance for your help!
