I have a fifteen year old outdoor timer which on certain days for NO obvious reason shuts off in the middle of a daytime automatic time session. The last time it shut off like this was perhaps two months ago. It just shut off a few moments ago as saw the spa water still from window. Other than being old as it was original timer any ideas ? Any one having this problem?
Have no idea about wiring since it works well and also when shuts off doesn't trip the breaker, just shuts off at say 3 pm during a time cycle between 9 am to 7 pm, or it may skip the start button completely and not start at all. again hasn't done this in two months or so but did today, thanks.
