PROHEAT AIR A2/A4 INSTALLATION MANUAL 6-2
ERROR CODES 6.2
CODE INDICATION CONDITION CHECK FOR
00 POWER FAILURE System voltage has dropped
below minimum requirement
or has been interrupted. • Code E00 is always displayed after the initial connection or
memory reset of the DCP to the heater.
• Disconnected or dead battery.
• Open fuse - there are two heater fuses to check, one located at
the heater and one in the battery compartment.
01 LOW VOLTAGE Input voltage is too low for
normal operation
.
• Weak or low battery (start vehicle engine to raise voltage and
recharge battery).
• Overloaded battery due to other appliances.
• Check heater voltage using Menu 08. For 12 volt systems, the
voltage must be greater than 10.5 volts. For 24 volt systems, the
voltage must be greater than 21 volts.
02 OVERVOLTAGE Input voltage is too high for
normal operation. • Alternator or other charging device may be interfering with
voltage – check heater input voltage at battery.
• Check heater voltage using Menu 08.
For 12 volt systems, the voltage must be lower than 16 volts and
for 24 volt systems lower than 30 volts. Over voltage must occur
for longer than 30 seconds to cause diagnostic code.
04 OVERHEAT BREAKER
OR
DISCONNECTED FUEL
PUMP • Blocked air ducting – check incoming and outgoing air ducts for
blockage or kinks.
• Disconnected fuel pump – check wiring at heater and at fuel
pump.
05 DISCONNECTED
GLOW PLUG • Check glow plug connection and ensure it is not disconnected
or loose.
12 UNSUCCESSFUL
START Heater Start Up Sequence has
timed out. • Check that fuel is being supplied to heater and that fuel lines to
heater are not damaged, blocked or kinked.
13 NO FLAME DETECTED Temperature in the combustion
chamber did not reach the
required temperature. • Check that fuel is being supplied to heater and that fuel lines to
heater are not damaged, blocked or kinked.
14 UNSUCCESSFUL
COOL DOWN Combustion chamber did not
cool down to the required
temperature in the time allowed. • Blocked air ducting – check incoming and outgoing air ducts for
blockage or kinks.
• Ensure heater shell casing is closed and secured.
Note: The heater will attempt a second cool
down cycle.
16 OVERHEATED AIR The temperature of the air input
is greater than 104°F (40°C)
during heating or 140°F (60°C)
during ventilation. • Intake air flow is too warm.
• Output heat air flow is too warm.
• Blocked air ducting – check incoming and outgoing air ducts for
blockage or kinks.
52 EXTERNAL TEMPERATURE
SENSOR – T3 The external temperature sensor
is no longer detected • Check for open connection between the sensor and the DCP.
60 MOTOR OVERCURRENT Excessive heater fan motor
current. • Check for object jamming the motor or fan blades.
• Check for objects on or around the heater causing pressure on the
fan or heater enclosure.
• Too much back pressure – check incoming and outgoing air ducts
for blockage or kinks.
Note: Other error codes are described in SB0053 available on the Proheat website.
