ATO Not Working As Expected

[Rob F]

Hi aquaalgae, I'm afraid the relay is going bad which you could probably verify with an AC volt meter. Put the probes in the outlet and see what voltage you get when it turns on/off. It's probably not always letting the full power through. Back in the day I use to work on two-way radios and one had a relay and this was a frequent problem. With those the lid could come off and after cleaning between the leafs it's was like new again. Obviously it's clicking ok so probably dirty contacts internally. I'll be happy to get away from these type, sorry but still probably a month away till the solid state one is ready.
