1. General information
This Service Manual describes the operation, disassembly, troubleshooting, and repair of Haier Room
Air Conditioners, etc. It is intended for use by authorized services who troubleshoot and repair these
units.
It is assumed that users of this manual are familiar with the use of tools and equipment used to
troubleshoot and repair electrical, mechanical, and refrigeration systems; and understand the
terminology used to describe and discuss them.
Haier urges you read and follow all safety precautions and warnings contained in this manual. Failure
to comply with safety information may result in severe personal injury or death.
Related Publications
This is a base service manual, covering a range of similar models. It is intended to be used in
conjunction with the Parts Manual and Technical Sheet covering specific model being serviced.
NOTE: General Precautions and Warnings
WARNING
To avoid risk of personal injury or death due to electrical shock, disconnect electrical power to unit
before attempting to service the unit.
WARNING
To avoid risk of personal injury or death due to electrical shock, DO NOT, under any circumstances,
alter the grounding plug .Air conditioner must be grounded at all times. Do not remove warning tag
from power cord. If a two-prong (non-grounding) wall receptacle is encountered, contact a qualified
electrician and have the receptacle replaced with a properly grounder wall receptacle in accordance
with the National Electrical Code.
WARNING
To avoid risk of heat exposure, which may cause death or severe illness, air conditioner must be
monitored when failures or shuts down.
WARNING
To avoid risk of personal injury or death due to electrical shock, grounding wires and wires colored like
grounding wires are NOT to be used as current carrying conductors. The standard accepted color
coding for ground wires is green or green with a yellow stripe. Electrical components such as the
compressor and fan motor are grounded through an individual wire attached to the electrical
component and to another part of the air conditioner. Grounding wires should not to be removed from
individual components while servicing, unless the component is to be removed and replaced. It is
extremely important to replace all removed grounding wires before completing service.

II. Temperature adjustment function
2.1 During temperature adjustment function, the operation frequency of outdoor unit will be based on
indoor temperature and the set temperature.
When air capacity operates automatically; the indoor fan will be controlled on the basis of the
requirements of temperature adjustment.
When the unit operates to make heat, the indoor wind unit will be controlled based on scrolling
temperature.

2.1.1 Standard of temperature sensor under indoor environment.
When the line is in short circuit or open circuit, the indicator light will be alarming and the indoor fan
motor will be off. It will resume to the original state automatically after it returns normally, and operates
as usual.
Short circuit:
Temperature: above 126 degrees,
Hex: Above F8H,
Value of Resistance: Below 0.65K, above 4.85V.
Normal temperature:
Temp: 25 degrees,
Hex: 40H,
Value of Resistance: 23K,
Voltage: 2.33V.
Power failure:
Temp: below -31 degrees,
Hex: below 08H,
Value of Resistance: Below 620K,
Voltage: Below 0.15V.
B parameter=4200
R (25degrees) =23K
2.1.2 Value of Resistance of indoor temperature sensor is ignored, when the heat mode is ON and the
indoor fan is OFF, as well as after warm start indoor fan operate for 30 seconds. (in order to avoid
affection of heat exchanger)
2.2 When frequency increase to holding frequency
In order to oil return fully during operating, the system will must keep some frequencies for a period of
time.
Time Indication Frequency indication
Drying in cool mode Heat Defrosting in heat mode Holding frequency
60 seconds 60 seconds 30 seconds 58Hz
After Forced operation OFF at the start status, system will begin to control the temperature area.
2.3 Preset temperature correction
The preset temperature is corrected according to the operating mode, air capacity and forced
operation status.
Only in the heat mode to correct the air capacity, confine to the low and middle speed of the air
capacity.
