What to do if my Goodman GSASD-18 unit does not function correctly and both power and performance lights are OFF?
- D
  daviddanielAug 16, 2025
  If your Goodman Air Cleaner isn't working and both the power light and performance indicator light are OFF, first ensure the system fan is turned on. Next, check the wiring to make sure it's properly connected and that the plug is inserted into a powered receptacle. If those aren't the issue, test the power switch for continuity with an ohmmeter and replace if defective. Finally, check the safety interlock by removing the door and pressing it with a screwdriver; if the lights come on, bend the interlock lever towards the front and close the door.

Why does my Goodman GSASD-18 Air Cleaner have an ozone odor?
- C
  Crystal MartinezAug 25, 2025
  An ozone odor from your Goodman Air Cleaner can be caused by several factors. Bent cell plates can be straightened with needle-nose pliers. Loose or broken ionizing wires should be replaced. Dirty cells require washing and cleaning of the ionizing wires. If the air cleaner is running when the system fan isn't, check the air switch and wiring. If the incoming voltage is too high, adjust the high voltage potentiometer clockwise on the power board. If the air cleaner is oversized, use the correct size. Extremely dry conditions in the home may require repairing or installing a central humidifier. Also, ensure the fan is running continuously and return air grilles are not obstructed to avoid heavy lint dust.

What to do if my Goodman GSASD-18 cells are not collecting dirt?
- T
  Terri BennettAug 27, 2025
  If the power light and performance indicator light are ON but the cells aren't collecting dirt, ensure the arrow on the cells is pointing towards the fan blower. Reposition the cell handle and place the cell in properly. Also, make sure the system fan is not on the “Automatic” setting; use the “Fan On” setting for continuous operation. Finally, try adjusting the high voltage potentiometer counter-clockwise on the power board to increase the voltage on the collecting cells.

How to fix a Goodman Air Cleaner cell that makes loud hissing noise?
- M
  melissawrightAug 31, 2025
  If your Goodman Air Cleaner cell makes a loud hissing noise or causes radio interference, the internal cell contacts might not be touching the plates; test and repair the contacts. Alternatively, the copper contacts on the high voltage tray may not be making a good connection on the cell; gently pull the contacts down with needle-nose pliers or replace the contacts.

What to do if my Goodman Air Cleaner cells are arcing excessively at the top?
- J
  Joshua BlackburnSep 4, 2025
  If the cells in your Goodman Air Cleaner are arcing excessively at the top near the copper contacts (with both the power light and performance indicator light ON), the copper contact on the high voltage contact board might be broken or bent upward. If possible, pull down the contacts with needle-nose pliers, or remove the power box and replace the contacts.

What to do if my Goodman Air Cleaner unit does not function correctly and the power light is ON but the performance indicator light is OFF?
- J
  jaredhartNov 12, 2025
  If your Goodman Air Cleaner's power light is ON but the performance indicator light is OFF, several issues could be the cause. There might be a short in the cells due to a broken ionizing wire (remove or replace wire fragments), large particles wedged between cell plates (shake out particles or wash cell), recently washed cells that are still wet (allow cells to dry completely), a dirty or damaged cell end plate insulator (clean or replace), or bent cell plates (straighten with pliers). It could also be a defective performance indicator light (test power board for high voltage; if present, replace the light), a defective power board (adjust the high voltage potentiometer or replace the board), a burnt-out Air Proving Switch (APS) sensor (blow lightly on the sensor or replace), insufficient...

What to do if my Goodman GSASD-18 Air Cleaner cells are arcing excessively?
- C
  Carrie VasquezNov 19, 2025
  If the power light and performance indicator light are ON or flashing, excessive arcing in the cells of your Goodman Air Cleaner could be due to several reasons. The cells might be wet from washing, in which case you should allow them to dry completely. There could also be particles lodged in the cell or a broken ionizing wire; try washing the cell, shaking out any particles, and replacing the wire if needed. Other potential causes include dirty cells (wash them and clean the ionizing wires), bent cell plates (remove cells and adjust to original spacing using needle-nose pliers), ducts that weren't cleaned prior to installation (clean the ducts), voltage that is too high (adjust the high voltage potentiometer on the power board clockwise), high voltage wires on the wrong copper contact (re...

Function Description

The High Efficiency Electronic Air Cleaner operates on the principle of electrostatic precipitation to remove airborne pollutants from the return air ducts of heating/cooling systems. It processes air through four stages of filtration:

Prefilters: These remove large visible particles like lint.
Ionizing Section: Smaller particles passing through are given a powerful positive electrical charge by ionizing wires.
Collecting Cells: Charged particles are then attracted to a series of grounded plates, where they are held like a magnet until cleaned.
Activated Carbon Filters (optional): These remove unpleasant odors from the air.

The cleaned air is then returned to the heating/cooling system. The unit is designed to operate only when the system fan is running, with an integrated Air Proving Switch (APS) automatically cycling the Air Cleaner on and off with the fan.

Wear safety glasses and work gloves when working on the equipment.
High voltage is present within the unit; extreme caution must be exercised during live tests.
Cells should be removed from the unit for most troubleshooting to prevent damage or injury from shorts.
Do not wash cells in a dishwasher or use objects to clean between plates, as this can cause damage. Do not place cells in an oven to dry.
