Without a functioning relay, my mower simply wouldn’t start, leaving me frustrated and unable to maintain my lawn.

Identifying Symptoms of a Faulty Starter Relay

I remember the signs that led me to suspect my starter relay. If my lawn mower made clicking sounds when I turned the key but didn’t start, it was a clear indication of a potential relay issue. Additionally, if the mower would start intermittently or not start at all, I knew I had to investigate further. Recognizing these symptoms early can save time and prevent further damage to my mower.

Choosing the Right Starter Relay
