One of my walk-in boxes is controlled by a temp gauge that operates a solenoid to close the liquid line and drop the suction pressure to trip the low pressure cut-off switch. The compressor is external and I did not notice until recently that the cut-off switch was not opening on pressure drop and the compressor was running constantly. The switch is a Texas Instruments PS80-02-F1009 015-005 and the system runs on R22. My supply house has another manufacturer's switch that cuts off at 10psi and cuts back in at 25psi. Will this switch function properly? And can I let the compressor continue to run constantly for another day or two until I replace the switch?
Any advice will be greatly appreciated. Bobby
