Fixing our Samsung Split Aircon Ourselves

Our Samsung 1HP non-inverter split air conditioner is now just about 8 many years outdated.  It has been in a visitor bedroom and has not observed that considerably use, but it has been trusted until a couple months ago.  Then, it refused to get started.  Opening up the situation we observed a lifeless lizard on the INDOOR circuit board.  We have had heaps of difficulties with lizards and the EXTERIOR circuit boards of our Samsung inverter, so considerably so that we received rid of the inverter rather than continually replacing circuit boards.   So, we have been faced with replacing the interior circuit board or buying a new break up device.  We did not hassle examining on the price tag of a new Samsung circuit board.  We assumed that if we went the Samsung service heart in Iloilo City, that alternatively than offering us the circuit board, they would want to agenda a company simply call.

The lousy circuit board was the one particular communicating with the remote handle and the thermostat.  We ended up able to take away the board and get the device managing, albeit with no remote and no thermostat — just on or off.  That was not very practical.  We were being unwilling to spend $100 or extra to take care of an 8 yr outdated device, so we looked for choices.  Remaining a enthusiast of Aliexpress (a subsidiary of Alibaba), we searched thorough the thermostat listing and uncovered a unit for $15 which include postage.   The device we acquired is a universal temperature machine, not built specially for air conditioners.  The characteristic that was key for us was that the device experienced a 30 amp relay, sufficient capacity  to start out the compressor.  We threw out most of the aged circuitry and related one particular aspect of the new thermostat to line (230 VAC electrical power) and to the other facet we connected the exterior compressor unit wiring and the within squirrel cage lover, definitely the only remaining elements of the device.  It worked.  Of class we really do not have a distant management, we really don’t have velocity management for the squirrel cage supporter and all the other features,  but we do have an operational, thermostatically managed split air con unit to use when we have company in our visitor bed room.  The $15 device has a spiffy LED exhibit demonstrating the higher temperature restrict (transform off), the latest temperature and the decrease temperature (transform on).  We set these to 28C for turn on and 26C for change off.  The device appears to have a time hold off to secure the compressor but the detain are a little bit unclear to individuals who really don’t read through Mandarin.
