Lennox water chiller

[tayler46]

HI

Ive got a 2002 lennox water chiller ( MODEL NO. WA-230-dkln). Its showing error code E79 on the lcd display inside the control box. Does anyone have a list of fault codes for this unit....and a wiring diagram.....or knows what e79 relates too? any help would be appreciated...


cheers

E79 compressor thermal overload, circuit A i believe, check motor protection device inside compressor terminal cover make sure you have 24v to it, also check compressor windings and motor klixon and contactors you can compare the readings to circuit b compressor.
Good luck ......LENNOX:mad::mad::mad::mad::mad::mad:

Cheers for that... Yeah LENNOX are a complete waste of time... spent nearly an hour on the phone trying to get a copy of a wiring diagram from them only to be told i need to email them... Despite telling the guy politely that on the roof of a 6 storey building didn't have any access to an email...

Almost as good as MERCURY CLIMATIC...!!!!!!!!!!
