Resetting your AC unit might seem intimidating at first, but don’t worry; we at bluco Mechanical are going to break it down for you into easy-to-follow steps.

Why Would You Want to Reset Your AC unit?

There are a few reasons, but the main one is a tripped breaker. Like most electrical appliances, an air conditioning unit has a circuit breaker. Two, to be exact. One is operating on the outside, and one is operating on the inside.
Generally speaking, a circuit breaker is a safety switch that protects your unit by immediately shutting it down when an overload is detected. It prevents fires and explosions. Once your power comes back after an outage, the sudden jump in electrical voltage can cause an overload in your unit’s circuit. It is when a circuit breaker kicks in.
Sometimes, after a breaker is tripped, your AC unit may not work as well as before. If you have it set at a cool temperature, but all you’re feeling is warm air — a quick reset is sometimes all you need.

How Do You Reset Your AC Unit?

Turn off your air conditioning system using the thermostat. You don’t want it to call your AC unit for cooling until after you’ve finished resetting it.
Search for the breaker box. Look for either a metal panel or a metal box placed flush against a wall. Sometimes it’s painted to blend in with your home, but usually, it’s a plain metallic colour.

It can be found in any of these areas:

Garage
Basement\sClosets
Laundry room
Crawl spaces

The exterior part of your home

Shut off your AC unit at the breaker. Search for the breaker switch that runs to your central heating and air conditioning system. Switch it to the “off” position.
Wait a full minute before switching the breaker back to the “on” position.
Wait for 30 minutes before turning your unit back on at the thermostat. It gives your system a chance to reset its internal circuit breaker.
Once the 30 minutes is up, carefully set your thermostat back to “cool”. To tell if everything is working properly, make sure you set the thermostat to at least five degrees below the room’s current temperature.
Simple, right? It gets even easier if you have a reset button on your AC unit that’ll perform this entire process for you. To check if your system has this button, you’ll need to look for it on your outdoor unit. Usually, it’s a big, red button. If you don’t see it or find it difficult to reach, it might be best to contact a professional to check your unit for you.

The quickest approach to fix an Amana PTAC device is to reset it. Continue reading to learn how to diagnose and reset an Amana PTAC.

Troubleshooting a PTAC

You can now troubleshoot your PTAC device without tools or technical skills. Your PTAC scans for problems in diagnostic mode and displays a unique code. Using the problem code as a guide, evaluate if a manual reset will fix your PTAC.

How to Diagnose Your PTAC

To test your PTAC unit, follow these steps:

Find the unit’s down and up arrow buttons.
Keep both buttons pressed.
Double-tap the “Cool” button on your PTAC unit.
Wait for the display to change.
In this case, your air conditioner should be in self-diagnostic mode. Look for a red dot blinking in the screen’s corner.
The PTAC’s display screen usually shows numbers indicating room temperature. Dashes (- -) replace these numerals in diagnostic mode. A green light may also be visible in the touchpad’s bottom left corner.
Allow the gadget to conduct a diagnostic test. After the test, the dashes will be replaced by an error code.
If the dashes remain, the system cannot notice the problem. Even resetting the Amana PTAC device may not fix the problem. Call an air conditioner repair technician.

FP

Your Amana PTAC device is currently in Freeze Protection mode. The Freeze Protection activates when the temperature drops below 40°F. It prevents components from freezing and damaging. Activate Freeze Protection by moving the unit to an area above 43°F.

HP

The “HP” fault number means the Amana PTAC is about to overheat. In this case, the device switches to Heat Sentinel mode to protect vital components.

Eo

“F1” denotes a twofold failure. The indoor thermistor (black) may be reading beyond the normal range, and the wireless thermostat may be broken.

F2

The indoor thermistor (black) is fine with this error code. But the wifi thermostat is broken. You’ll need an AC repair expert to fix it.

F3

The thermostat is ideal. However, the indoor thermistor (black) is not.
