MD11 50 SR Blowing fuse 307 when reches temperature

[Chris2005]

Hi All

I have a problem with a thermo king MD11 50 SR that happens about once a week,

sometimes when it reaches temperature it blows fuse 307 , I have checked wires and found the HP switch wire was rubbed through , repaired that but still blowing fuses.


Regards

Chris

is the diode ok on the throttle solenoid? or is it happening when its shuts down on cycle sentry?

Hi

Thanks for your reply

I had the lorry in for a day to see what was going on.

It turned out to be a wire rubbed through for the defrost damper coil in where the return air probe is located.

Many Thanks

Chris
