What it is
Carrier's service manual says to check the outdoor coil for clogging by ice or debris, and clean or de-ice it if necessary, for its high and low pressure faults (31, 32, 83 and 84). Goodman's manual says to check and clean the condenser coil for its L2 high-side fault.
How to choose
- Follow your manual for how it says to clean the coil and avoid anything that bends the fins.
- A fin comb can straighten lightly bent fins; the comb has to match the fin spacing, so measure it before buying.
- Use a product labelled for the coil type.
How it is tested
- Look at the outdoor coil for leaves, cottonwood, grass clippings or ice.
How to use it
- Turn off the outdoor disconnect and the breaker before cleaning. Clear loose debris gently. Do not open panels or touch electrical parts.
Capacitors can hold a charge after the power is off. Safety terms.
