EvaKool Fridge

I have the RF47 and it gets down to -18 and lower on a setting of around 7 on normal. I don't get frost on much of the evaporator and from my quite limited knowledge of refrigeration I believe that the less frost the better.

At the temperatures you are setting it at, yes it would normally frost up the panel.

Does the unit run for longer periods than it used to?

I had a problem with mine after about 10 years it ran for excessive time and eventually wouldn't shut off at all. It needed re gassing. Back to normal now.

Hi Rowdy,
I have found their after sales service very good and helpful.
Best shot would be to give them a call and see what they say.

With fridge running near maximum, check the frost line on your evaporator plate (bit in the fridge thats white with tubes in it.

You should get frosting over all the tube lines (for want of a better term) and then the waffle plate at the end, where it goes square, instead of a straight tube, should also frost on maximum.
This is where the final evaporation takes place so you dont get liquid refrigerant over run on the suction side of your compressor.

If not, then your down on refrigerant charge, meaning there is not enough to be pumped through the capillary tube, and into the low pressure side in the evaporator where it does just that, evaporates from a liquid to a gas, thats the noise you can hear of it evaporating when the compressor turns off and you hear it bubble away.
Thats what causes the fridge to cool, or absorb heat.

If a low charge, then all the pumped liquid evaporates before it reaches the end of the evaporator tubes and waffle plate, thus not cooling like it could, even with the compressor running non stop.
You most often see a line where it is evaporating to and thus cold, then its no longer frost but moisture where it can no longer cool due to insufficient refrigerant charge.

Remedy is to vac down your system, check and find leaks if any, fix, then correctly recharge with required refrigerant checking amp draw and the frosting line on the evaporator to ensure its correctly charged, as some systems may take a bit more than others or less.
Just topping is not really the answer, as it brings in other problems, or may cover over an existing one.

This applies to all fridges, hope that you find this helpful.

cheers
