Mitsi Heavy Fault

[coolments]

Hi All

Mitsi Heavy Industries: SRK50ZD-S wall mount

Just round at a friends and his AC wont heat, so naturally I take a look.

Unit works fine in cooling, when switched over to heating it runs for around a minute then stops and the timer light on the front blinks twice, sure its trying to tell me something but not being a Mitsi Heavy fan i dont have any manuals for them.

Messed about and found the following, if i pull the power on the reversing valve while the unit calls for heating then the unit will not lock out and run meerily away thinking its heating, so i thought its a sensor problem and pulled them of the coils to see if that helped but no.

Any one else had this problem or have a manual handy to tell me what the timer light flashing is telling me.

Outdoor heat exchanger liquid pipe sensor error

Broken heat exchanger liquid pipe sensor wire, poor connector connection

When a liquid pipe sensor wire disconnection is detected while operation is stopped. (If a temperature of –50ºC or lower is detected for 15 seconds, it is judged that the wire is disconnected.) (Not displayed during operation.)

Thanks for reply Nike I will order a sensor and go back, also armed with manuals.
