π Introduction: Year-Round Comfort Starts with the Right Settings
One of the key advantages of the Amana 9,200 BTU Through-the-Wall AC with Heat Pump is its ability to provide both cooling in summer and heating in winter β all from the same compact, wall-mounted unit.
But if you're like Mark, a homeowner looking for simplicity and efficiency, you might wonder:
"How exactly do I switch modes on my Amana wall unit β and how can I be sure it's working the way I want it to?"
This guide explains everything:
-
How the mode switching works
-
What each setting on your remote or control panel means
-
How to avoid common pitfalls
-
Tips for optimal comfort and efficiency
ποΈ 1. Understanding Your Amana Unitβs Control Panel & Remote
Your Amana wall unit comes with either:
-
A touch-sensitive control panel on the front panel
-
A wireless remote control (often with LCD screen)
π Common Buttons You'll See:
Button | Function |
---|---|
Mode | Switches between Cool, Heat, Fan, Auto, Dry |
Fan | Adjusts fan speed (Low, Med, High, Auto) |
Temp β²βΌ | Sets the desired temperature |
On/Off | Powers the unit |
Swing | Controls louver direction (if available) |
π The βModeβ button is what youβll use to switch between heating and cooling.
π¬οΈ 2. How to Switch from Cooling to Heating (and Vice Versa)
Hereβs a step-by-step guide for Mark and other homeowners using either the remote or control panel:
π² Using the Remote:
-
Press βOnβ to power up the unit
-
Press the βModeβ button until βHeatβ appears on the display
-
Use the Temp β²βΌ to set your desired room temperature
-
The unit will activate heating mode and reverse refrigerant flow
To switch back to Cooling, repeat the same steps and stop when the display shows βCool.β
π§± Using the Built-In Panel:
-
Tap the Mode icon to cycle through operating modes
-
Stop when the HEAT indicator illuminates
-
Adjust setpoint temperature with β² or βΌ
π Remember: Switching modes may take up to 3β5 minutes to fully transition, especially for heat pump reversal.
β οΈ 3. Important Things to Know When Switching Modes
π§ 1. Donβt Rapidly Switch Between Modes
-
Let the system complete its cycle before switching again
-
Rapid toggling can stress the compressor or trigger a safety lockout
π₯ 2. Heating Mode Requires Outdoor Coil Defrost
-
If you hear a clicking or buzzing during heating, the unit may be defrosting the coil
-
This is normal and temporary
π§― 3. Power Off Before Long-Term Inactivity
-
Leaving the system in Auto mode may cause unneeded cycling during spring/fall

π§ 4. What Each Mode Actually Does
Mode | Function | Best Use |
---|---|---|
Cool | Cools room to set temperature | Summer or hot days |
Heat | Heats room to set temperature | Winter or cold nights |
Fan | Circulates air only | Spring/fall ventilation |
Auto | System picks heat/cool as needed | Transitional seasons |
Dry | Dehumidifies without major cooling | Humid, rainy days |
π« Markβs Tip:
βDonβt use Dry mode thinking itβll heat or cool β itβs just for removing humidity. Great for stormy weather, though.β
π 5. What If Your Unit Wonβt Switch Modes?
Before calling for service, try these troubleshooting steps:
π 1. Check the Remote
-
Replace the batteries
-
Reset remote by removing batteries for 60 seconds
β‘ 2. Power Cycle the Unit
-
Unplug for 5 minutes and plug back in
-
This resets internal circuit board
π§° 3. Check the Temperature Setpoint
-
Heat mode wonβt engage if the room is already warm
-
Cool mode wonβt activate if the set temp is higher than room temp
π οΈ 4. Check for Obstructions
-
Filters or vents blocked = improper airflow
If nothing helps, contact a certified technician to inspect the reversing valve or thermostat control board.
