Test Condensate Pump and Float Switch
If the internal condensate pump does not operate, the pump may be bad or the oat switch may be defective. Perform the
following test:
1. Access the electrical control box.
2. Unplug the oat switch from the circuit board.
3. The pump should start.
4. If the pump does not start, check for voltage at the pump connector on the board. There should be 230 Volts AC to the pump.
If there is not, the circuit board is defective. If there is proper voltage to the pump, either the pump or associated pump wiring
is defective.
