Error Code [5201] - Mitsubishi Electric PUHY-HP200YNW-A Service Handbook

[7-7 Error Code Definitions and Solutions: Codes [5000 - 5999] ]
7-7-4

Error Code [5201]

1. Error code definition
High-pressure sensor fault (63HS1)
2. Error definition and error detection method
If the high pressure sensor detects 0.098MPa [14psi] or less during the operation, the outdoor unit stops once, turns to anti-
restart mode for 3 minutes, and restarts after 3 minutes when the detected high pressure sensor is 0.098MPa [14psi] or more.
If the high pressure sensor detects 0.098MPa [14psi] or less just before the restart, the outdoor unit makes an error stop, and
the error code "5201" will appear.
During 3-minute antirestart mode, preliminary errors will be displayed on the LED display.
A error is not detected for 3 minutes after the compressor start, during defrost operation, or 3 minutes after defrost operation.
3. Cause, check method and remedy
(1) High pressure sensor failure
(2) Pressure drop due to refrigerant leak
(3) Torn wire coating
(4) A pin on the male connector is missing or contact failure
(5) Disconnected wire
(6) High pressure sensor input circuit failure on the control board
7-7-5 Error Code [5301] Detail Code 115
1. Error code definition

2. Error definition and error detection method
When the formula "output current < 1.8 Arms" remains satisfied for 10 seconds while the inverter is in operation.
3. Cause, check method and remedy
Cause
(1) Contact failure
(2) INV output phase loss
(3) ACCT sensor failure
(4) Compressor failure
(5) INV board failure
