lrp sphere tc warranty

[spindles69]

I've had this controller for about five years.Been faultless up until last week when it just stopped working.Took case apart and there was a lot of dried dirt and small pieces of grass under the case.Thats probably why its stopped working?Just wondered whether anyone has sent one back on warranty and how you got on.Don't want to just throw it away because i have another three in my buggies that ive had no problems with.
Cheers Mick.
