PROBLEMS & SOLUTIONS
On rare occasion the TX200 may seem to be performing differently or not at all. Experience has
shown that varying operating conditions can affect the performance characteristics of the TX200. The
temperature of the cooling system will affect how the TX200 performs.
Following are typical problems with explanations of the possible cause and solution.
PROBLEM: My TX200 was recovering refrigerant and the Compressor On light went OFF which
indicates the cooling system should be in a vacuum. However, the Manifold Gauge still
shows a pressure.
SOLUTION Determine if the Condenser Fan is still running. The fan can be heard and air flow
through the TX200 can be felt. If the fan is running, the high pressure switch has shut
the TX200 off due to an over-pressure condition.
Turn the Power Switch OFF and then ON. The condition may correct itself.
This over-pressure will typically be due to excessive pressure in the cylinder caused
by Air. Check the cylinder pressure and purge air as described previously.
PROBLEM: My TX200 worked fine all last Summer. I got it out today for the first service job this
Spring and it is very slow in evacuating the cooling system.
SOLUTION: Today's Spring temperature may be much lower than the average temperatures during
the summer months.
The refrigerant in the cooling system will not be under as high a pressure at lower
temperatures and the TX200 will take longer to draw a vacuum. More cycles may be
required to completely recover the refrigerant.
PROBLEM: I can not get the TX200 to draw a vacuum.
SOLUTION: Check Manifold Gauge and Hoses for restrictions or leaks.
