trying to figure out whats going on with a rheem classic 90 +. It stoped worikng last week, I opened it up to check it out and didnt see anything wrong. came back later and it seemed to work fine.
It died again yesterday and gave it another look, this time I looked at the manual and there was a referance to a blinking LED. the code for the said 1 HR lockout.
The manual that was left does not explain the problem or cure for this.
Anyone know whats up ?
