Refrigeration Tips?

[beno]

Has anyone come across any tips or tricks to determine if a refrigeration unit has a weak compressor or is shorts of gas WITHOUT putting a line tap and gauges on?

I heard on the grapevine that there are ways?

Any suggestions are greatly appreciated!

This one may work to find out is there is lack of gas , place lighter on pipework as it comes out of the compressor in theory I will absorbe the heat if its still hot it suggests there is lack of gas.

Obviously partial freezing or an iceballing on a wetwall/skin evapourator is another indicator.

I would not have thought this would have been an issue with the small ammount of gas that the system would have contained, 100grms etc
other alternative is to put a cannary in the fridge or freezer compartment :rotfl:

I guess you have never been at the wrong end of an isobutane blowlamp!!

Point taken with the Blowlamp, Obviously common sense would apply where a system would be low on gas and care would need to be taken but if there was a big leak most of the gas would have been dispersed into the atmosphere and not forgeting that the correct mixture of gas and air would be needed to cause an explosion.

The suggestion to use a lighter as I have used has never caused me any problems but before I test an area with heat I would test with a soapy solution to check for any bubbles and this has never failed me.
