Sensor Shorted

System will operate on maximum A/C and high blower only.

Calibration can be checked by disconnecting service connector and checking resistance across the two red wire terminals. Maximum resistance should be 1850 ohms at 65°F, 1400 ohms at 75°F, and 1070 ohms at 85°F. Test for open or shorted condition with an ohmmeter.
