frigidaire r5303b 2006/2007 model, tripping rcd???

as in description, it seems to be tripping out, not been around it long enough to find out if its when the t/stat cuts out, but just a quicky post to find out if thats possible, or if its more likely something serious in the compressor??? iirc the relays must be built into the comps on these, as connect said they werent available as a separate part.

cheers for any advice, cust is scatty and convinced its the ghost of her deceased partner giving her a sign :eeek: as shes got a new “boy”friend now 😐
