Motor will
not start.
10
1/2 HP Furnace Electric Motor
Possible Cause(s)
1. There is a blown
fuse or open circuit
breaker.
2. Motor starter
overload activated.
3. The thermal switch
is open.
4. Low or no voltage
reaching motor.
5. Power enters
control circuit but
does not reach the
motor.
Suggested Solution(s)
1. Test for voltage at the fuse or circuit
breaker. Also see if the voltage/amp
rating of the fuse or circuit breaker is
correct for the motor. It should exceed
the Motor's FLC by 25 percent.
2. The thermal protector will automatically
reset and the motor will function
normally again once it has cooled. Test
the starter before starting motor again.
3. The thermal protector will automatically
reset and the motor will function
normally again once it has cooled.
Beware as the motor may automatically
start when reset.
4. Check each motor terminal's voltage.
The voltage should be within 10% of
the voltage on the motor's nameplate.
Disconnect the load and apply power to
the motor. If the motor operates
normally, then the issue is with the load
attached to the motor. Should the
motor still not work, have it serviced or
replaced by a qualified technician.
5. Begin by confirming all contacts
are clean and tight. Examine for
obvious damage.
a. Test each part of the circuit for
power until the problem area is
discovered.
b. Have a qualified service technician
repair or replace the circuit.
