AAF-McQuay MQLDT1100-0 060006301 Control Board
 |
AAF‑McQuay MQLDT1100‑0 060006301 is a MicroTech II energy‑management keypad and control panel used on AAF‑HermanNelson classroom unit ventilators. Common failures include backlight or LCD display loss, keypad button drift, power‑supply tripping (often from the 24 V DC rail), and firmware corruption that causes the panel to lock or fail to communicate with the main controller. First‑check diagnostics: verify the 24 V input voltage and continuity of the power supply; inspect the LCD backlight driver and keypad connectors for loose solder joints or corrosion; review any error codes displayed on the panel or logged in the host system’s diagnostic interface.[oss-gpt-20b] |
