Condenser Solenoid Valve

1. Set the voltmeter to the 250 VAC scale.
2. Set the ON/OFF switch to the ON position.
3. Set the TIMED/MANUAL switch to the MANUAL position.
4. Check for outflow at the dram opening.
• If water flows from the drain, continue this procedure with step 5.
• If no water flows from the drain, continue this procedure with step 6.
5. Set the TIMED/MANUAL switch to the TIMED position, and check for outflow at the
drain opening.
• If water flows from the drain, the condenser solenoid valve is good. End this
procedure here.
• If no water flows from the drain, the condenser solenoid valve is faulty. Replace
the condenser solenoid valve.
6. Check for 120 VAC across the condenser solenoid terminals.
• If the meter does not read 120 VAC across the solenoid terminals, continue this
procedure with step 7.
• If the meter reads 120 VAC across the solenoid terminals, either the solenoid
valve is faulty or the plumbing is blocked to or from the valve.
a. Check for blocked or damaged tubing and fittings between the condenser
and drain valves. Replace faulty fittings and tubing.
b. If the tubing and fittings are good, the condenser solenoid valve is faulty.
Replace the condenser solenoid valve.
7. Refer to Heater Contactor Test (Figure 5-22) and check for 120 VAC across the coil
terminals of the heater contactor.
• If the meter does not read 120 VAC across the coil terminals of the heater
contactor, continue this procedure with step 8.
• If the meter reads 120 VAC across the coil terminals of the heater contactor, the
condenser solenoid wiring is faulty. Check the brown, brown/white, and red
condenser solenoid wiring for continuity and secure connections. Replace or
repair faulty wiring and connections.
8. Check for 120 VAC from the TIMED/MANUAL switch orange wire connection to the
ON/OFF switch white/black wire connection.
• If the meter does not read 120 VAC between these TIMED/MANUAL and
ON/OFF switch wire connections, the fault is not in the condenser solenoid
valve. Test the TIMED/MANUAL switch.
• If the meter reads 120 VAC between these TIMED/MANUAL and ON/OFF
switch wire connections, the condenser solenoid wiring is faulty. Check the
brown, white/brown, orange, and black wires of condenser solenoid wiring for
continuity, and secure connections. Replace or repair faulty wiring and
connections.
• (For key pad timer units only) If the meter reads 120 VAC between these
TIMED/MANUAL and ON/OFF switch wire connections, the condenser solenoid
wiring is not faulty.
