The blower is part of the heater’s combustion system. Part 416816 crosses to Eberspächer part number 252069992000, also formatted as 25.2069.99.2000.

This blower motor is intended for compatible first-generation 12-volt Airtronic D2 heaters. It is not the correct replacement for 24-volt D2 heaters or newer Airtronic S2 D2L heater models.

The 334183 Airtronic D2 blower gasket should be inspected and replaced as needed when installing the blower. Other related D2 combustion components include the 417745 flame tube, 334181 burner gasket, 420453 glow-pin assembly and 416820 flame and overheat sensor.

Always verify the heater model, voltage and identification number before ordering. Similar Eberspächer heater models may use different blower assemblies.

• Airtronic S2 D2L heaters
• Applications requiring a different blower part number
• Heaters that have not been positively identified

Confirm compatibility using the heater identification label and complete heater number before ordering.

Common Service Applications

The blower motor may be replaced when:

• The blower motor does not operate
• The blower operates intermittently
• The blower is physically damaged
• The motor or fan assembly is worn
• Internal inspection identifies blower damage
• The heater is undergoing a comprehensive rebuild
• Combustion-system service requires blower replacement
• A technician has diagnosed the blower as the failed component

A heater fault, shutdown or no-start condition does not automatically confirm blower failure. The complete heater should be properly diagnosed before replacement parts are ordered.

Important Installation Notes

• Confirm that the heater operates on 12 volts.
• Confirm that the heater is a compatible first-generation Airtronic D2.
• Disconnect electrical power and fuel before servicing the heater.
• Inspect the electrical connector and wiring before installation.
• Inspect the blower wheel and surrounding housing for debris or damage.
• Inspect the 334183 blower-motor gasket during disassembly.
• Replace damaged, compressed or deteriorated sealing components.
• Inspect the flame tube and burner components while the heater is open.
• Clean the mating surfaces before reassembly.
• Do not substitute a 24-volt blower motor.
• Reassemble the heater according to the applicable service procedures.
• Test heater operation after completing the repair.
• Heater service should be performed by a technician familiar with diesel-fired air heaters.
