Westinghouse 410l fridge trips new RCD's in fusebox
What causes our 1995 Westinghouse 410 litre fridge freezer to trip the new RCD's (earth leakage device) in my house fusebox? Is there an easy fix for this? Would replacing it with a 1991 Hoover 410 litre cyclic fridge be successful?

Tripping an earth leakage would indicate a break down of insulation in the windings of the compressor, the possibility of a short circuit in the wiring system or the defrost element down to earth. I recommend you have a certified technician check it out before you have a fire. If the Hoover is in good condition there is no reason not to replace it. Rate me please.

not necessary-- yet-- to buy a new unit
tripping the rcd is an indication of earth leakage which could amount to water in the wall plug across pins, moisture across the power board, water in the motor, faulty heater element
what you need is an accredited electrician to run tests on the system to find the reason for the earth leakage that is tripping the rcd
the rcd works from microvolts and operates in nano seconds to prevent electrocution of the operator
testing before buying may save heaps of cash
It may be possible the defrost heater is shorting to earth or ground. This would trip the GFI every time the refrigerator went into defrost. It also is possible that water has infiltrated the insulation and causing a leakage current. This would be much harder to fix.
Is your FREEZER is plugged into a wall socket which is protected by an EARTH LEAKAGE UNIT or RCD [Residual Current Device] ???
Most manufacturers advise NOT to have this type of appliance connected through an RCD as the start load required when the COMPRESSOR "kicks in" is quite large [especially in larger fridge/freezer units] AND will quite often TRIP your RCD. These appliances are better connected to a separate electrical circuit if at all possible and not protected by an RCD.
The elements in ovens consist of an outer earthed metal tube and an inner resistive element that is insulated from the outer tube by what is effectively a compressed ceramic insulating powder. If the element is not used for a while, enough atmospheric moisture, (or from spills, etc), can penetrate the insulation to cause enough earth leakage to trip the RCD. If the RCD is tripping at the correct level, (They can get too sensitive - see this article here: Diagnosing RCD earth leakage breaker nuisance trips), then the only long term solution is to replace the element, although they can sometimes be dried out by heating them.
Ensure it fully dries out before trying it again. Water in the electrics will throw your trip instantly. If it's dry now, and you are having the same problem. check the electrics for a short circuit or earth fault. Usually a compressor earth fault is to blame.
IF the warranty is still in effect, call for service. IF no warranty, then check the heaters for the solid inks. Probably a bad element, or a shorted element. Unless you are skilled with electrical meters, V-O-M type, this could be dangerous. DO NOT ATTEMPT to troubleshoot this with power on. IF you can use a meter, with the power OFF, check for continuity and resistance with multi-meter set to Ohms. BE CAREFUL! Electricity can KILL!
If random then the compressor has earth leakage when under load. Compressor is faulty. If water flow is disrupted and water filter light comes on for replacement for ice maker/cold water then this can cause an earth leak that will trip the rcd
I assume by "earth leakage" you mean it is on a GFI circuit? Some older GFI outlets are sensitive to and do not work well with motors or other inductive loads like your refridgerator compressor. As for the compressor feeling hot, this is usually normal.
If this is a GFI outlet, try replacing it with new unit. If it is a GFI breaker, try replacing that.
Hi akula, 200 ks to a fridgie, LG appliance, you must be in Australia;) Is it the earth leakage circuit breaker operating. If so, then you have a leakage problem to earth from the heater pad(not quite sure what that is, but this problem will need to be repaired. Am doing some research to see if there is anything that can be done without just getting a new fridge. Back to you soon.
