CHECK 1EVCON COIL
• ACTIVATION: Evaporator fan motor contactor (1EVCON) circuit is shorted or open.
• UNIT CONTROL: Engine and Electric Operation: Alarm only.
• RESET CONDITION: Auto Reset or alarm may be manually reset via keypad or by turning the unit off,
then back on again.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, the active
alarm should clear itself (see reset condition above). Operate the unit through the appropriate modes to see if
any active alarm occurs. Continue with the steps below as necessary.
CORRECTIVE ACTIONS:
1.
Check 1EVCON
a. Inspect contactor coil and terminals. Verify there is no damage to coil, and no damage or corrosion
to terminals.
b. Check contactor coil resistance. Refer to
for contactor coil resistance values. Cannot
be opened (infinite ohms), shorted (Zero Ohms) or shorted to ground.
2.
Check 1EVCON Using Component Test Mode
a. Use Component Test Mode to energize 1EVCON. (Refer to
.) Verify Current Draw
on Component Test Mode Screen. Refer to
for correct electrical values.
b. Check coil voltage between A1 and A2. Verify 12 VDC between A1 & A2.
c. Check resistance at contacts. Verify contacts are closed at L1
−
T1, L2
−
T2, L3
−
T3.
3.
Check 1EVCON Wiring
Inspect harness & control box connector pins & terminals. (See wiring schematic
) Verify
there is no physical damage to harness. Verify there is no damage, moisture, or corrosion in connectors.
