Checking the PFC Reactor
Checking the Outdoor Unit Sensors
Checking the Reversing Valve Coil
NOTE: Component resistance readings shown in this section
based on model being tested.
Testing of the following components requires the use of an
ohmmeter and temperature probe.
NOTE: Use needle probes only, and probe the back or side
contacts of the plug to obtain the reading. Do not try to
probe the connector end of the plug, as this may damage the
contacts of the plug.
NOTE: Use respective temperature / sensor chart for sensor
type being tested.
Compressor discharge sensor
Suction sensor
Tube sensor (defrost temperature)
Ambient sensor
Step 1
Disconnect the sensor plug from the control board for this
test. Failure to do so may provide inaccurate readings.
Step 2
k-type temperature probe, determine the temperature of
the sensor.
Step 3
Using an ohmmeter, check the resistance value of the sensor.
Step 4
Referring to the temperature / resistance table
specific table,
verify the resistance value corresponds to the temperature
shorted, or outside
Step 5
Re-seat the plug on the connector at the conclusion of the
test.
Step 1
Disconnect the reversing valve plug from the control
board connector for this test. Failure to do so may provide
inaccurate readings.
Step 2
Step 3
Re-seat the plug on the connector at the conclusion of the
test.
Step 1
Disconnect the DC Fan Motor plug from the control board
connector for this test. Failure to do so may provide
inaccurate readings.
Step 2
Refer to the chart shown below for plug pin combinations and
resistance values.
Note: Test is polarity sensitive, adhere to probe placement as
shown in chart.
Step 3
Re-seat the plug on the connector at the conclusion of the
test.
Step 1
Disconnect the EEV Stepper Motor plug from the control
board connector for this test. Failure to do so may provide
inaccurate readings.
Step 2
Refer to the chart shown below for plug pin combinations and
resistance values.
Step 3
Re-seat the plug on the connector at the conclusion of the
test.
Step 1
Disconnect wires from terminals LI and LO of the power
module board.
Step 2
Using an Ohmmeter, check the resistance value of the PFC
Reactor. The resistance value of the coil is less than 1 Ohm.
checked in step 2.Replace the sensor if the reading is open,
Using an ohmmeter, test the coil to make sure it is not open,
shorted, or grounded. The 09k and 12k models have a four way
units normally found in mini-split systems.Rather than the
voltage applied to the valve coil remaining as long as the call for
heat is active, the Tempo 115 VAC models apply momentary
valve (4WV) that operates differently from the standard 230 VAC
power in the 103 to 126 VAC range. This power remains long
enough to switch the valve piston from cooling to heating mode.
Since the refrigerant pressure flowing from the valve body
capillary tube holds the piston in place, allowing hot gas to
redirect into the indoor coil, the VAC signal is no longer needed
and is removed by the PCB.18k and 24k models will read
230 VAC across the coil as long as the unit is in the heating
(energized) mode.
