E8 means the unit is limiting or stopping operation because temperatures are getting too high during the cycle. For a homeowner, the first useful check is airflow: a dirty filter, blocked return, or blocked outlet can make the indoor coil run outside the expected range. Manual trigger: E8 means high-temperature prevention protection is active.

Urgency
advisory
This is not usually an immediate safety hazard, but do not keep resetting it. Try the safe homeowner check below; if the code comes back, schedule service.
Likely causes
Temperature sensor reading out of range
Loose sensor connector or damaged sensor lead
Moisture, corrosion, or vibration affecting the sensor circuit
Control board input fault after the sensor checks out
Homeowner fix
Clean the washable filters. If a filter is damaged or packed with debris that will not rinse out, replace it with the exact filter for your indoor model, then reset once. Expected result: airflow improves and E8 clears; if it returns, stop there.

When to call a pro
Call a licensed HVAC technician if E8 returns after filters and airflow are corrected, or if the indoor fan does not move air normally. Tell them the code is high-temperature prevention protection.
Repair vs replace
A filter or airflow correction is low cost. If a technician confirms a refrigerant or control fault on older equipment, compare the repair with replacement.
