When a furnace stops working or suffers from performance degradation, this can relate to several reasons. Some of these include broken hoses and dirty filters. However, if a professional from an air conditioning service in Cypress, TX, clears out these issues, then the most obvious culprit is your thermostat.
According to a professional of an air conditioning service in Cypress, TX, a thermostat may malfunction due to the following issues:
- They can degrade due to aging and faulty wiring.
- Without proper maintenance, a large amount of dust can accumulate in the thermostat.
- Sometimes, even extreme temperature can damage thermostats.
All of the issues mentioned above can prevent your thermostat from working, which means that its connection with the heating equipment suffers. As a consequence, regulation of air also suffers. Let’s have a peek at some of the most usual thermostat-related problems that can sabotage your furnace. If you find any of them, contact a reliable air conditioning service in Cypress, TX.
1. Power Issues
Check your thermostat’s display and observe how it is indicating power. If it does not show any power, try for a battery replacement as the first solution. If it turns on at irregular times, make sure that it uses AA Lithium batteries. Experts from an air conditioning service in Cypress, TX, explain that thermostats with alkaline batteries cannot operate well. These batteries deplete quicker and can trigger frequent failures to your thermostats.
If the problem does not stem from your batteries, shift your focus to the power switch. Sometimes, this switch is unintentionally turned off. If it is not the switch, then most probably, the problem may originate from a circuit breaker or a fuse. Therefore, ask an air conditioning service in Cypress, TX, what exactly is causing the power problem.
2. Misaligned Components
According to an experienced professional from an air conditioning service in Cypress, TX, optimal operation of a furnace is not possible without it matching correctly with your thermostat. In residential homes, low-voltage thermostats are frequently installed. To match your thermostat with your heating steam, a lot of considerations come into play such as the capacity, capability, type, and size of the furnace.
If an unmatched thermostat is installed, it can produce miscommunication, culminating in the failure of your heating system. For correct matching, an expert will have to inspect your thermostat and compare it with your furnace.
3. Unstable Wiring
It is possible that the wiring of your thermostat is aging, faulty, loose, or disconnected. Such wiring issues can make a severe impact on its connection with your HVAC system, especially your furnace. As a consequence, an interruption is caused due to which your rooms cannot get hot air. Therefore, whenever your furnace does not work properly, you can examine the wiring of your thermostats. If you have doubts on the wiring, have a professional from an air conditioning service in Cypress, TX, tighten or replace them accordingly.
4. Debris Accumulation
If your thermostat is not subjected to regular cleaning, it can become dirty. With the passage of time, dust and debris can accumulate in the thermostat, which in turn results in an unsteady operation. To tackle this problem, you can take out the thermostat’s cover. Subsequently, clean the interior parts of your thermostat carefully – mainly the switch contact surfaces and the bimetallic coil.
To begin your cleaning procedure, modify the settings of your thermostat and set it to the lowest configuration. Afterward, you can utilize a soft brush for cleaning the bimetallic coil. Now, set it to the highest setting, and repair the thermostat again. Lastly, perform a reset of the thermostat and set it to your desired setting.
5. Malfunctioning of the Heat Anticipator
Non-digital, mechanical thermostats contain an electrical resistor component – a mounted and tiny metal tab. It is known as a heat anticipator and directs the thermostat on when to disable the burners of the furnace.
If anticipator malfunctions, it can inflict significant damage to the furnace .i.e. the furnace can cycle on/off more often than required. Such an anticipator needs adjustment for rectification.
On the other hand, programmable and digital thermostats come with built-in anticipators which provide automatic adjustment, eliminating the need for manual settings.
To adjust mechanical thermostats, a technician from an air conditioning service in Cypress, TX, uses an amp meter for determining the suitable setting. At times, they simply just bi-directly push the anticipator to fix them.
6. Irregular Temperature Readings
Malfunctioned furnaces can turn or turn off erratically. If your furnace starts when it shouldn’t, or fails to start when it should, your thermostat may be displaying wrong temperature readings.
Make sure that your thermostat is located in an appropriate area. An ideal thermostat location is away from heat sources – like radiant heaters and fireplaces – and windows and outside doors.
It is worthwhile to remember if your thermostat is exposed to the outside temperatures, heat emissions, and, direct sunlight, it will show inaccurate readings. As a result, your furnace cannot function properly and may turn on and turn off unsteadily.
According to a technician from a reputable air conditioning service in Cypress, TX, thermostats are best installed near the return – at the filter location – to ensure error-free temperature readings.
Additionally, sometimes the drafts that originate from the region behind your thermostat also trigger wrong readings. For such a case, an expert may use insulation to stop it from influencing your thermostat.
