Keep getting CH62 error, "temp. above 87 degrees"; it's been serviced, gas removed-weighed-replaced. Nothing wrong with it. Trips out with CH62 when temp. Above 30 degrees. Any ideas?

Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! The thermistor that monitors the heat sink may be out of range and needing to be replaced, the outdoor unit may need to be cleaned or there may be an issue with air flow. Are the outdoor cooling fins clean?

Inverter over 85°C. Check air flow across heat sink, check inverter tight to heatsink use thermal paste. Multi V - check inverter cooling fan
