What it means
F7 means ipm module temperature protection. In plain English, the system is protecting itself because a coil, compressor discharge line, or power module temperature is outside the expected range.
Urgency
advisory
Do the safe airflow checks once. If it returns, schedule service.
Likely causes
- Dirty filter, dirty coil, or blocked air path
- Fan motor running slowly or not running
- Temperature sensor loose, failed, or misreading
- Refrigerant flow, charge, or restriction problem
Homeowner fix
Turn the system off. Clean only the user-removable indoor filter and clear loose outdoor debris without removing panels. Reset once after the unit has time to cool.
When to call a pro
Call a licensed HVAC technician if F7 returns after one safe reset or the condition will not clear. Tell them the official source lists F7 as IPM module temperature protection.
