RobinAir 34800 2K control board
 |
The RobinAir 34800‑2K is a dual recovery/recycling controller used for R‑12 and R‑134a refrigerant systems; it monitors pressure, temperature, flow and drives the compressor/valve actuators. Common failures include burned‑out MOSFETs or relays on the power rail, damaged capacitors in the input filter, and shorted signal lines to the pressure transducers. Start by verifying that the 24 V DC supply is within spec and that all ground connections are secure; then visually inspect the board for burn marks or swollen electrolytics, and use a multimeter to test continuity of the relay contacts and MOSFET drain‑source paths. If the board passes these checks, review any error codes displayed on the unit’s LCD and cross‑check them against the service manual for known fault conditions.[oss-gpt-20b] |
