I bought a Portable Air Conditioner HPY12XCN and it cools

Customer Question

Hi I bought a Portable Air Conditioner HPY12XCN and it cools great, but as it cools the thermostat jumps up to 95. Is it reading the exhaust temperature for some reason? Also the fan rattles on high.

Thanks for counting on us to help with your appliance problem. My name is ***** ***** I look forward to helping you! It is likely the thermistor connection that is loose or corroded. The control reads the temperature as a resistance from the sensor, so if the connection has issues, the resistance will be higher. As for the rattling fan, if the blade is very dusty, that may just need to be cleaned. Are you able to disassemble the unit for inspection?
