Paragon 7218‑00 is a 7‑day industrial time switch that drives up to 40 A per pole with a 120 V timing motor and NEMA‑3 enclosure. Common failures on this model include worn or broken timing motor bearings, burnt contacts in the 2N.O./2N.C. contact packs, and corrosion of internal wiring due to moisture ingress. The unit may also exhibit mis‑timing if the internal clock crystal fails or if the reset/override switches are stuck.

First‑check diagnostics: verify that the power supply is delivering clean 120 V AC at the rated frequency; inspect the motor windings for continuity and signs of overheating; examine all contacts for pitting or burn marks and replace any that show wear. If the unit still fails, review the internal error logs (if available) and perform a visual inspection of the enclosure for water ingress or rust that could be affecting the circuitry.[oss-gpt-20b]
