If your furnace is short-cycling, check the filter first — a clogged filter causes the limit switch to trip. If the filter is clean, then the switch itself may be failing.

Description
A low-pressure switch protects your compressor by shutting the system down if refrigerant pressure drops too low (which usually means low charge or a restriction). If your AC shuts off and won’t restart for a while, the low-pressure switch may be tripping — or it may need replacement.
