The refrigerator run loud for twenty minutes or so then it stops for ten minutes and starts running loud again

It's a normal noise! When the liquid refrigerant becomes less pressurised, usually when the thermostat clicks off,, it still bubbles through the system until the pressure equalises.

The only temperature sensitive part I can think of is the condenser. In most saws it is under the flywheel with the points. Some newer saws have an electronic ignition module. If that is the case the module must be replaced.

Sounds like your fuel pump is going out. Next time it doesn't start, cycle the key from off to run position (not start) and listen for the soft hum of fuel pump. If it's not there, you need a new pump.

YOU ARE BE GETTING A WEEK COMPRESSOR.

Sounds like the freezer fan is rubbing some wires or possible some foam insulation around the fan. I would look into the freezer compartment fan and go from there. The fan Will Shut off when you open the doors. Let me know how you make out and if you need anymore help.

Thanks,

Frost on the low side line means the system is overcharged (too much freon).  Look on the tag insided the fridge and it will tell you how much freon it holds.  Usually 4.25-5.50 ounces on average.  The loud noise sounds like you have air in the system.  I would evacuate, from the high side while running, and let it run empty for 5-10 minutes.  Then while running put the valve core back in the high side.  Then unplug the fridge and charge with proper amount of freon thru the high side.  Wait about 5-10 minutes and plug back in.  Normal low side pressure should be 0-3 psi.  This is a good indicator of the proper amount of freon in a good working system.
