Hi everyone! New to this, so bear with me...

I have a 'LP Equalisation' fault on an Airedale EasiCool type: V26X2 – EZRE – 0

The compressor runs for approximately 20 seconds then the suction pressure falls to zero, which to me indicates a problem with the electronic expansion valve? No signs of any visible leaks and the standing pressure on the suction is around 7 bar. Anyone give me some advice?

Cheers
