expansion noise mitsubishi srk50

Post by forte123 » Thu Nov 16, 2017 6:07 pm


Sometimes my inverter has periods of expansion noise with drop outs, then after 3 minutes (pump start protectoin?) this repeats again and again.

When this happens, it even doesn't reach room temperature any more because of the dropouts.

On max. power it functions normally (15 min.)

What causes this problem exactly ?

Thanks for your quick reply!
