Digital Thermostat – Troubleshooting Common Digital Thermostat Problems
Digital Thermostat — Solve My Digital Thermostat Issues
Although an installed digital thermostat typically functions trouble-free, perhaps you can benefit by the following simple testing processes. After all, a faulty thermostat affects the heating and cooling comfort level throughout your entire home.
In this article, the techs at Arizona-based American Cooling and Heating works to help you better understand how to resolve problems with your Mesa home HVAC command system – the digital thermostat solution.
5 Steps to Basic Digital Thermostat Troubleshooting
Before leaping into the basic steps in digital thermostat troubleshooting, confirm that your thermostat is turned on, set to heat or cool depending on your desired comfort level, and that the fan system is also on. It also helps to reset the system. Do this by turning the thermostat off, pressing the reset option, and then turning the thermostat back on. If you lack understanding on how to turn a thermostat on and off, and you also lack access to a user manual, best option – Contact your local ACH comfort system specialist.
1) Thermostat Sensor
Testing for a faulty thermostat sensor merely requires that you have some alternative method for measuring room temperature. For the professional Arizona HVAC tech, the measurement is instant and accurate. After all: Your Mesa A/C professional does utilize an array of highly sensitive, extremely accurate and somewhat costly HVAC tool kit. However, for a homeowner not pushed for immediate answers, a simple alcohol or mercury thermometer is sufficient for this test. In the room to be tested, just mount one of these inexpensive temperature measurement devices and then wait an hour or so to take a reading. Any discrepancy between the room temperature and the readout shown on your digital thermostat implies that your system has a faulty thermostat sensor.
Repairing a Faulty Thermostat Sensor
Repair or replace is rather senseless, and not at all cost effective. When dealing with a faulty thermostat sensor, best solution is that you replace the entire unit. However, before leaping directly to the stage that involves thermostat replacement, continue reading this report.
2) Calibrate The Thermostat According To Room Temp
Perhaps your digital thermostat is merely in need of calibration. Different makes and models of thermostats function according to different specs. For accurate unit calibration, we recommend calling in your local Arizona HVAC tech. However, it is likely that your thermostat instruction manual includes directions concerning calibration of the unit. If you lack access to a manual, some digital thermostats include calibrations instructions on the inside of the unit cover.
3) Checking Thermostat Wiring Connections
Ok. So the sensors are not faulty, and calibration is completed. Next step involves checking thermostat wiring for the likes of:
- Corroded connections
- Broken wiring
- AND Direct shorts.
Start by disabling incoming thermostat power sources. Be careful. Any contact with life electrical wiring can result in serious personal injury. Once you have confirmed that incoming thermostat power is disabled, remove the unit from the wall so that you can visibly examine the wiring connections. Look for corrosion, direct breaks in connection, and loose connections. If wire nuts are not installed, correct that issue before reinstalling the unit.
Important Safety and System Warning…
