SECTION 5 - TROUBLESHOOTING

SYMPTOM

POSSIBLE CAUSE

CORRECTIVE ACTION

FAN RUNS BUT NO HEATING.

(ELECTRIC HEAT UNITS)

No power to electric heat
circuit on units with dual point
power.

Establish power to electric heat circuit.

Loose or improper wiring from
thermostat to electric heat
contactor.

Verify all wiring connections and terminations, and verify
proper wiring of thermostat.

Loose or improper wiring of
electric heat element.

Verify all wiring connections and terminations, and verify
proper wiring of electric heat element.

Defective electric heat
contactor.

With electric heat contactor energized, verify proper
voltage on contactor load terminals. Replace as

required.

Tripped or defective primary
high limit switch.

Turn thermostat to lowest set point and allow fan to run
10-15 minutes for limit switch to cool and reset. Then
turn thermostat to highest set point and check for proper
heating operation. If high limit trips again, check for the
following conditions: improper voltage to heater element;

obstructed fan or unit outlet reducing air flow over heater

element; dirty or defective heater element causing hot

spot. If heater does not operate after sufficient time

for limit switch to cool, disconnect power and check
continuity across primary high limit switch. Replace if
defective.

Tripped secondary high limit
switch.

Secondary high limit switches are designed to trip only
during extreme failure conditions. Contact factory before
attempting any corrective action.

Defective thermostat.

Momentarily jumper thermostat contacts to simulate

proper operation. Replace thermostat as required.

Defective electric heat
element.

Disconnect power and check continuity through heat

element. Replace as required.

Improper aquastat or change

over relay operation on units

so equipped. (Note: electric

heat will not operate when
hot water is present at the
unit.)

Verify proper aquastat position on piping, and verify
proper aquastat and change over relay operation.
Replace as required.
