Room Air Conditioner Parts

This main control PWB is the appliance's primary electronic control board that manages user inputs and cycle functions, restoring normal control when a faulty board causes operational issues. What it does:

• Receives user commands and runs appliance control algorithms
• Powers and updates the touchpad/display and indicator lights
• Manages timing, relay switching, and communication with sensors
• Common symptom: appliance won't start, has a blank or erratic display, or shows control-related error codes
• Helps correct unresponsive buttons, intermittent operation, or unexpected cycle behavior when board failure is confirmed

• Disconnect power (unplug or shut off breaker) before accessing the control board
• Handle the PWB by its edges and avoid static discharge; use ESD protection if available
• Refer to the appliance wiring diagram and service manual for proper connector placement and safety procedures

This transformer supplies the low-voltage power needed by the appliance's control and ignition systems, restoring proper operation of electronic controls and spark ignition when the original transformer fails. What it does:

• Converts incoming mains power into the low-voltage output used by control boards and igniters
• Supports reliable spark generation for gas ignition systems on compatible appliances
• Helps restore responsive electronic controls and displays when a failed transformer causes loss of power
• Prevents intermittent control or ignition failures caused by a defective transformer

• One transformer

• Disconnect power to the appliance before starting any repair to avoid shock or injury
• Handle wiring harnesses and connectors carefully; ensure secure connections and proper routing

This is an electronic control board (PC board) for a room air conditioner. It manages the unit's charging and operational functions, communicating signals from the touch pad to control cooling, fan speed, and temperature settings. Replace this board if your air conditioner is unresponsive to controls, displays erratic behavior, or fails to turn on.

Hex flange nut with 10-32 thread secures components in appliances. Replace if stripped, missing, or damaged. Flange provides broader bearing surface.

Replace your air conditioner's touch pad control panel if buttons are cracked, worn, or unresponsive. Installs on the front interface for user controls.

This electronic PC board controls key appliance functions and user interface signals so the unit responds correctly to button presses and cycles. Replacing a failed board restores electronic control without replacing other modules. What it does:

• Receives input from the control panel and sends commands to motors, valves, heaters, and lights
• Manages timing and sequence for cycles and electronic features
• Can cause symptoms like an unresponsive control panel, blank or erratic display, or failure to start cycles
• Helps resolve intermittent operation or loss of specific electronic functions when board failure is the confirmed cause

• One electronic PC board

• Disconnect power (unplug or trip circuit breaker) before starting work
• Handle the board by edges and avoid static discharge—use an ESD strap if available
• Verify connector orientation and seating; ensure all harnesses are fully engaged before testing
• Test appliance operation after installation; if other symptoms persist, further diagnostics may be required

This is the main electronic control board for a room air conditioner, managing compressor operation, fan speeds, temperature regulation, and user inputs. It mounts behind the control panel and connects to the display, sensors, and motor components. Replace this board if the air conditioner does not turn on, fails to respond to controls, displays error codes, or does not maintain the set temperature.

This is the main electronic control board (PC board) that manages the core functions of a portable or window air conditioner, including compressor cycling, fan speed, and temperature regulation. It processes input from the control panel and sensors to maintain the desired settings. Replace this board if the unit does not turn on, displays error codes, fails to cool, or if buttons and controls are unresponsive despite receiving power.

This printed circuit board serves as the main electronic control for the air conditioner, processing input from the touch pad and managing functions like temperature, fan speed, and mode selection. It mounts behind the front control panel and connects to the unit's sensors and components. Replace this board if the display is unresponsive, buttons do not register, or the unit behaves erratically.

This is a printed circuit (PC) board that manages the electronic functions of a room air conditioner, including temperature regulation, fan speed, and mode selection. It receives input from the control panel and directs the compressor, fan motor, and other components accordingly. Replace this board if the air conditioner is unresponsive to controls, displays error codes, or fails to turn on despite receiving power.

This is the main electronic control board assembly for a room air conditioner, incorporating the touch pad control panel. It processes user inputs and regulates compressor, fan, and temperature functions. Replace this board if the unit fails to respond to button presses, displays error codes, or does not turn on or cycle properly.

Replace your cracked, unresponsive, or worn air conditioner touch pad control panel. Installs on the front display area to restore button functionality.

This is the main electronic control board (PC board) that manages the operating functions of a room air conditioner, including temperature settings, fan speeds, and mode selection. It receives input from the touch pad or control panel and controls the compressor and fan circuits accordingly. Replace this board if the unit does not respond to button presses, displays error codes, or fails to turn on despite receiving power.

Replacement exhaust hose screen for room air conditioners. Installs over exhaust outlet to filter debris. Replace if cracked, broken, or missing.

Air conditioner not cooling or fan not spinning? This motor replacement restores airflow and cooling performance. Moderate DIY repair in 1-2 hours.

This fan blade moves air across the condenser coils in your air conditioner's outdoor unit to remove heat from the refrigerant. Proper airflow through the condenser is essential for efficient cooling performance. Replace this blade if your air conditioner runs but doesn't cool effectively, makes unusual noises, or if you notice the outdoor fan isn't spinning.
