The most typical Thermostat Problems And Their Solutions
Have you ever noticed air conditioning systems switching on and off by themselves When you have a conventional electric oven, you must have observed that heating coils stop heating after some time. Why does this happen and what causes it It happens because in both the cases mentioned above, there is a manually set temperature, which when attained, a device turns the system off, thereby stopping the flow of heat, uni dimmer touch so that a desired set temperature could be maintained. The device accountable for regulating the temperature is named a thermostat. So now, you possibly can imagine that any problem with thermostat can cause numerous discomfort. Without it, one could have to manage the temperatures manually, whenever we feel too hot or too cold. So, let’s quickly take a look at the issues and troubleshooting for a thermostat.
Commonest Thermostat Problems
First signs of problems with a thermostat include drop in performance of the temperature regulating system, and can make you are feeling too warm or too cold. Before calling out an A/C repair professional, it can be worthwhile to look on the thermostat yourself.
Crucial factor you have to see is the place of installation. When you have the thermostat mounted on a wall with a high thermal coefficient, then such a device will fail to give you comfortable temperature, because it won’t ever react properly to the air within the room. But instead, it should clock the temperature of the walls. Similarly, if they are installed at places where there’s direct sunlight or near an out of doors door or window, you’ll face the same problem. Ideally, a thermostat’s installation must be near where the filter is, so that it may possibly sense and react to the temperature within the air handler.
Be sure there isn’t a hole or empty space behind the thermostat. Such an area can feed cool or warm air currents to its back. In the event you happen to note an enormous hole at the back of the thermostat, you possibly can stuff some insulation on this hole, like cotton gauze, or cover it with non-conducting tape. On mechanical (non-digital) thermostats, a heat anticipator is installed which needs to be set in accordance to the current draw on the thermostat circuit. This anticipator may need periodic manual adjustments with the help of an amp meter to get a correct setting.
Any sort of thermostat is always susceptible to dirt problems. The dust and grime that builds up inside the thermostat will hinder its working. What you are able to do is open up the front panel of the thermostat and clean the dirt using a small and light brush. Dust especially (and very carefully) around the contact points; that is where the dust causes most of its problems.
This is the most obvious problem. If your thermostat is old and not working as it used to, just replace it. As with all electronic or mechanical equipment, the thermostat will work worse the older it gets. And replacing parts won’t help much. You’ll just find yourself periodically replacing something or the other. Rather buy a new one and be done with it.
Some thermostats, mostly digital ones, use battery power for their functioning. It is likely to be a simple case of the battery getting discharged, or a malfunctioning of the battery recharging system. Inspect the batteries and replace them if required. Some digital thermostats are designed for AA batteries, or if there are back lights, then they could use AAA batteries. In case you think that the charger has some issues, ensure to check the ability switch circuit breaker within the battery charging circuit.
Most thermostats utilized in homes are powered by 24 volts AC, and this power is derived from an air handler and heating split system. Such thermostats are known to be equipped with a power stealing technology. In such cases, it is best to first check the circuit breaker meant for the air handler and ensure it isn’t tripped. It isn’t uncommon for people to forgo these circuit breakers and that’s after they think the thermostat is out of order.
Loosely-wired or Miswired
HVAC systems are not to be trifled with. Lots of people get the notion that they will fix a broken thermostat, as it is just a matter of twiddling with a couple of wires. Chances are high, they will end up smoking the control boards or the transformer. Unless you might have good experience in HVAC installations, I strongly advise that you just get your thermostat looked up by an expert. Because you’re not just messing with a bit of electrical equipment that costs a good chunk of cash, you’re risking your personal self while tinkering with it. In truth, you may often come across forums that uni dimmer touch deny any DIY help to people who are new to this, because they know the chance involved. And while we’re at it, in no case will you open up the thermostat while the power continues to be on. Make you you trip not only the outer breakers, but the inner home breakers as well.
As of late, most A/C systems are equipped with programmable thermostats. The largest problem in such devices is their RAM-like programming chips. These thermostat chips lose their programming whenever there may be an abrupt power failure. To get rid of this case, you might want to reprogram the chip, but it is going to meet an identical ending whenever there’s another power failure. As of late newer programmable thermostats are available which have a ROM memory which does not perish with a power failure. But, if the old system does not support these new programmable thermostats, the only option is to go for conventional battery powered ones.
These are the main problems that are highly prevalent in air conditioning systems. Despite the fact that temperature control systems have become technologically superior, improper usage and non-standard installation can damage the system and cause trouble.
