P7
Gree Split AC
Severity: ModerateWhat Does This Error Mean?
P7 means the IPM (Intelligent Power Module) sensor circuit has a fault. The IPM cannot safely monitor its own temperature or current without this sensor. This usually requires a technician to inspect or replace the outdoor drive board.
Affected Models
- Gree FAIRY Series
- Gree LOMO Series
- Gree U-MATCH Series
- Gree PULAR Series
- Gree Inverter Split System
Common Causes
- Sensor wire inside the IPM or drive board is broken
- Temperature or current sensor component on the IPM board has failed
- Poor solder joint on the sensor circuit from vibration over time
- Moisture ingress into the outdoor unit damaged the sensor circuit
- IPM module itself is failing and needs replacement
How to Fix It
-
Turn off the AC and switch off the outdoor unit circuit breaker.
P7 is an internal board fault — there is no DIY fix for this, but powering down protects the IPM from further damage.
-
Allow the outdoor unit to cool for 30 minutes before any inspection.
The IPM can retain heat and dangerous voltage after shutdown — always allow adequate cool-down time.
-
Check the outdoor unit for signs of moisture or water ingress.
Water damage to the electrical compartment is a common root cause of P7 on older units.
-
Call a Gree-certified technician for board-level diagnosis.
The technician will test the sensor circuit and determine if the drive board or IPM module needs replacement.
-
Ask about a like-for-like board replacement if the unit is still under warranty.
Gree warranty covers drive board replacement for manufacturing defects within the warranty period.
When to Call a Professional
Call a technician to diagnose a P7 error. The IPM is a high-voltage component inside the outdoor unit and must only be handled by qualified personnel. Do not attempt to open the outdoor electrical compartment without proper electrical knowledge.
Frequently Asked Questions
What is the IPM in a Gree AC unit?
IPM stands for Intelligent Power Module. It is the main switching component in the outdoor inverter drive board that controls compressor speed. It contains built-in sensors to protect itself from overheating and overcurrent.
Can I fix a Gree P7 error myself?
Not safely. The IPM and drive board operate at dangerous voltages even after the unit is switched off. This is a job for a qualified HVAC or electronics technician.
Does P7 mean I need a whole new outdoor unit?
No — in most cases just the drive board or IPM module is replaced. Full outdoor unit replacement is only considered if multiple components have failed simultaneously or the unit is very old.
