摘要

A heater for a motor vehicle heater comprises a burner with a combustion air blower. A series resistor is fitted for part-load operation. This resistor is arranged in a casing (2, 6) surrounding the electric motor (4) driving the blower impeller (14) of the combustion air blower (1) through which combustion air is taken to cool the electric motor and the resistor (24). The resistor is soldered to a printed circuit board (20) located radially on the casing downstream in relation to a combustion air passage aperture (22) in the form of a cut-out in the board. The printed circuit board preferably has an insulating plate with a cut-out (36) in the region of the resistor.
