Check voltage between COM and Load terminal (should be 100-240V AC). | | Load switches sporadically / chattering | Ambient temperature exceeds 55°C or AC supply has excessive spikes. | Add external varistor (Model: V150ZA05P). Reduce load current by 30%. | | One output stuck ON | Thyristor short-circuited due to inductive kickback. | Replace module. Add diode+sistor snubber on future installs. | | All outputs dead | Internal 5V DC-DC converter failed (common after 20 years). | DC voltage check across pins 2 & 3 of IC7 (per page 28 manual). | mitsubishi tost1t manual exclusive
