FAULT CODE / TROUBLESHOOTING
014 - TEMPERATURE DIFFERENCE BETWEEN FLAME SENSOR AND OVERHEAT
SENSOR TO LARGE
1. Using shop air, blow out the heat exchanger and airow ducting including the intake.
2. Check airow ensuring the ducting is free from obstructions especially the bunk inlet and outlet.
3. Check ducting rating of the installed heater. See page 33.
4. Remove the sensor, check connections, wire and reinstall.
5. If the wiring is damaged or connection is corroded, replace the sensor, otherwise continue below.
6. Check fuel pump angle and correct if needed.
7. If correction was needed, clear the fault and run unit.
8. If fault code doesn’t return complete the job, otherwise continue below.
9. Measure fuel quantity.
a. Disconnect the fuel line from heater.
b. Turn the unit on (remember 60 second delay prior to pump activation).
c. Place the fuel line into the graduated cylinder and allow to run through a rst start attempt.
d. Once fuel pump stops running from rst start attempt turn the unit off.
e. Measured fuel must be between 3.5 to 4.3 milliliters.
10. If the reading is high and the pump angle is veried correct, replace the pump, clear the codes, and run the unit.
11.If the reading is low, and the pump angle is veried correct, replace the inlet lter and retest
12.If fault code doesn’t return complete the job otherwise continue below.
13.Replace the sensor.
015 - OVERHEAT WITH EXCESSIVE TEMPERATURES
1. Sensor has detected excessive temperatures.
2. This code indicates that Code 017 was set and the unit was restarted.
3. This code indicates that the heaters has been overheated repeatedly consecutive times.
4. Unlock control unit by reviewing all codes.
a. Document all codes.
b. Clear codes (once codes are cleared the lockout will be cleared)
5. Using shop air, blow out the heat exchanger and airow ducting including the intake.
6. Check airow ensuring the ducting is free from obstructions especially the bunk inlet and outlet.
7. Check ducting rating of the installed heater. See page 33.
8. Remove the sensor, check connections, wiring and reinstall.
9. If the wiring is damaged or connection is corroded, replace the sensor, otherwise continue below.
10. Run unit.
11.If Code (either 015 or 017) returns replace the sensor.
12.Clear code and run unit.
13.If code returns reinstall original sensor and replace control unit.
14.Run unit ensuring issue is resolved.
016 - OVERHEAT WITH EXCESSIVE TEMPERATURE
1. This code is set when excess temperature is seen at the overheat sensor.
2. See Code 015.
019 - GLOW PIN POWER CONSUMED BY GLOW PIN IS TOO LOW
1. Unplug the glow pin.
2. Inspect the wire and plug condition; if damaged replace the glow pin, otherwise plug back in.
Take care when working with the glow pin - damaged wires or broken glow pins are not a warrantable failure.
Do not twist the wiring during removal. See Basic Repair Analysis Guide / Non-Genuine – glow pins failing under warranty must be returned
3. Clear codes and run unit.
4. If code returns replace the glow pin.
5. Clear codes and run unit.
6. If code returns replace control unit and reinstalled the removed glow pin.
020 - OPEN CIRCUIT - GLOW PIN (BE CAREFUL NOT TO PULL WIRES OFF GLOW PIN DURING REMOVAL)
1. Inspect glow pin leads for continuity, replace if necessary
2. Check for corrosion in terminals (maintenance)
021 - SHORT CIRCUIT - GLOW PIN (BE CAREFUL NOT TO PULL WIRES OFF GLOW PIN DURING REMOVAL)
1. Inspect glow pin leads for continuity, replace if necessary.
2. Check for corrosion in terminals (maintenance).
