Cooling tune up performed today on an Amana two stage heat pump installed in 2020. All electrical connections are tight with no corrosion. Thermostat is saying there is an outdoor temperature sensor communication error. Checked both the outdoor air temp sensor and the outdoor coil temp sensor and both sensors are coming at 9.5ohms. This error code should not effect the system in cooling mode. Indoor air handler is clean. Filter was changed on this visit. Outdoor unit was washed and waxed and all of the leaves in the bottom were vacuumed out. System is running and cooling the home upon departure.
