Is capacitor bulged or oily?

Ask Your Own HVAC Question
Customer reply replied 8 years ago
im at work ? is the capacitor located in the service panel, or in the compressor area?
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 8 years ago
Service panel with wires leading to fan motor. The capacitor with normal appearance has a recessed flat surface on the top. When blown the top bulges. Sometimes the capacitor may not show visible damage...then it must be tested with a meter. If the fan wants to start...and with help by spinning will start...is usually bad capacitor. If the unit has power and when "helped" feels resistant, it usually bad motor.

Can you tell if the compressor in the bottom is running?

Ask Your Own HVAC Question
Customer reply replied 8 years ago
how do i determine if it running?
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 8 years ago
You would hear it and the 2 copper lines that run from outside to inside will have distinct temperature differences.
