2. Cleaning the Condenser Coils
- You have to aim your garden nozzle in the condenser coil to remove the crud build-up.
- Then clean the crud around the coil. Now flush the debris under the coil fins with the nozzle.
- Now make the water flow gently out of the nozzle. Shoot water directly into the coils to remove the remaining dirt and debris.

To examine the fuses in the disconnect block you have to set the multimeter to the low Ohms scale. Now touch the red and black leads that are on the opposite ends of the fuse.
- If you get a reading then the fuse is good.
- But if there is a zero, infinity symbol (∞) or minus then the fuse is blown.
4. Examining the Access Panel
