Watlow A007-1298- REV H Circuit Board
 |
The Watlow A007‑1298 Rev H is a high‑current (140 A) industrial temperature control board used in furnaces and ovens, operating from 115/230 VAC with a 200–600 °F range. Common failure points on this class of boards include burnt or cracked MOSFETs, damaged IGBT drivers, failed thermistor or RTD sensing elements, and degraded capacitors or inductors that can cause voltage spikes. First‑check diagnostics: verify the incoming AC supply and ensure proper grounding; inspect the board for visual signs of component damage (burn marks, bulging caps); test the MOSFET/IGBT on‑off switching with a multimeter and confirm thermistor resistance within spec; review any error codes displayed by the oven controller or associated PLC.[oss-gpt-20b] |
