4.32 RESISTORS (R1-R7) This task covers inspection, testing, removal and installation
Tool kit, service, refrigeration unit (Item 1, Appendix B)
Disconnect input power to the air conditioner before performing any internal
maintenance. Voltages used can KILL. Shutting the unit off at the control panel does not
disconnect unit power
(1) Disconnect air conditioner input power at source,
Check resistors for signs of overheating or other visible damage Replace if damaged (see fig 4-23).
Using multimeter, measure each resistor for proper resistance Resistance should measure 2850-3150 ohms. Replace if
Unsolder damaged resistors (2) and remove from resistor board (1).
Solder resistors (2) to resistor board (1).
