MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTiON
1. HEATER DOES NOT START
NOTE
Igniter, ignition control, flame detector switch, and overheat switch test good or have
been replaced.
Step 1. Remove guard (page 2-42).
Step 2. Check shut-off solenoid (1) as follows:
a. Start heater (page 2-59).
b. Using multimeter set for resistance, put red probe on terminal (2) and black
probe to good ground.
If multimeter reading is not 130-140 ohms, replace solenoid(1) (10560C24,
10560M and 10560G, page 3-74; 10560M24B1, page 3-88).
c. Turn off heater (page 2-61).
Step 3. Check for proper igniter voltage as follows:
a.
b.
c.
Set multimeter for dc voltage measurements.
Place red multimeter probe on output terminal of ignition control (3) and black
probe on ground.
StarI heater (page 2-59).
If multimeter reading is more than 12.0 volts, replace voltage limiter assembly
(10560C24, 10560G, page 3-1 14; 10560M, I0560M24BI, page 3-1 16).
