Why My Thermostat Clicks but Nothing Happens?

You probably rely on the thermostat to keep the air in the room relaxed and comfortable, no matter the temperature outside. You expect your home to be at a pleasant temperature when you return home following a long day at work. If you come into a house that is either freezing or uncomfortably hot, it might be a disturbing experience. When your thermostat beeps, but there’s no heat or air, what should you do?

Unfortunately, owners who have a thermometer that clicks but does not heat their home are frequently contacted by professional Roofing technicians. The thermostat does indeed click, but nothing happens after that. Which is the most likely cause of this inconvenient situation? The following are the most effective methods for resolving the issue independently.

The thermostat makes a clicking sound, but nothing happens. Your thermostat may be set incorrectly. To get the furnace to turn on, set the thermostat to a temperature that needs the air to be heated. You will find answers to some of the frequently asked questions.

1. Replace your air filters

If you have several pets or allergies, you might wish to change them every month. The airflow into the furnace is impeded when the air filters get clogged with dust, dirt, pet dander, or other material.

If there isn’t enough airflow entering the unit, the furnace will hardly produce heat. Before you do anything else, spend a few bucks on new high-quality air filters. This could be one of the most fundamental reasons the thermostat clicks, but no heat or air is being produced.

2. Clean the pilot ignitor

Over time, the pilot ignitor may get clogged with debris and accumulation, rendering it unable to light the furnace when the thermostat is turned on, and the door is opened. You won’t be able to warm your home during the cold winter nights unless you have this ignition.

Taking the front panel off your furnace and peeking inside will allow you to determine if the pilot ignitor causes the problem. If you can choose whether or not this is a contributing factor to the thermostat clicking but not producing heat, it will be easier to direct your repair efforts in the proper direction.

The critical thing to remember is that you should only be inspecting the pilot ignitor in the furnace at any given time. The actual cleaning must be left to the hands of a trained professional. Maintaining this component can be incredibly difficult and sometimes dangerous for the average layperson.

3. Correct your setting

Correct your setting

But nothing happens when the thermostat is activated. The reason for this could be that your thermostat is set at the incorrect temperature. Before turning on the furnace, set the thermostat to a level that needs the air to be warmed before turning on the stove. To test the device, you can increase the specified temperature by a sufficient amount.

All of your thermostat’s other settings are also important. Inspect your thermostat to ensure that it is adjusted to the right season. The system switch must be set to “heat” or “auto during the winter months.” As well as turning on or auto, the fan should be turned on.

4. Check your breaker

If your thermostat is clicking, but your furnace is not starting, one of the most likely causes is no power. Although it appears to be one of the initial things to look for, many homeowners overlook this phase in their house inspection process.

The switch has likely been tripped due to a recent energy spike in your home. It’s no surprise that the thermostat continues to click even if there is no heat or air conditioning present. After you have checked your home’s breaker box, you should also check to see that the furnace is operational.

5. Turn the gas supply on

Homeowners with a gas furnace should ensure that their gas valves are properly opened, especially if the thermostat clicks but does not provide any heat. Please turn it on slowly and watch whether the burner begins to fire up.

If you notice the smell of gas, turn off the valve and call your local gas provider right away to report it. If you see this, it is a warning that you’ll have a leak, which is quite dangerous. Taking care of gas leaks should be left to the specialists because it can create long-term harm and the structure of your house. This is one instance in which a do-it-yourself solution should never be advocated.

6. Seek professional help

Seek professional help

You may do numerous things on your own at home to remedy a thermometer that clicks but does not produce any heat or air conditioning. The majority of these actions take only a few minutes, but they have the potential to save you hundreds of thousands of dollars in repair fees.

If these do-it-yourself tactics are ineffective, bringing in a professional HVAC technician may be necessary. A much more significant issue may be at play that the typical homeowner cannot resolve.

Don’t be scared to contact your local heating and air conditioning provider. When the thermostat clicks and nothing occurs, it can be unpleasant to live in your own house for a while. By seeking assistance, you can get it under control more quickly.

Most of the time, a thermostat that clicks is a good indicator. It makes this noise to signal that the thermostat has detected a higher or lower temperature than your preferred setting. The sound indicates that the heater or cooler should be turned on immediately to bring the indoor temperature down to a comfortable level. Unfortunately, this is not always the case.

Another possible explanation for your thermostats on/off cycling is a faulty thermostat. It is possible that the heater or cooler is not functioning if the thermostat clicks, but nothing else happens. Although there may be a problem with the wiring somewhere down the line, it is more commonly the consequence of a problem with the actual heating and air conditioning system.

First, double-check your wiring, as well as any batteries or extension cords. This will ensure that you haven’t overlooked anything important. Following your confirmation that the thermostat and cables are functioning correctly, it’s time to inspect the heater or cooler for malfunctions.

A gas leak in a cooler, for example, or a broken element inside the machine are also common difficulties. In addition, you could be running low on gas. When you use propane or other organic gasses, you have cylinders or a gas line that can become clogged, causing the system to become inoperable.

Check the indicators on the propane tanks to make sure they are working correctly. In some cases, simply changing the line to a full tank would address the problem. In the case of any natural gas pipelines, first and foremost, make sure that your bill is current. The thermometer will work and make a clicking sound if the gas is turned off, but nothing else will occur.

Next, check to see if there isn’t a gas leak in the area. The smell of rotten eggs added to gas is quite noticeable, so this particular addition is utilized. When there isn’t an evident leak, though, you should contact the gas utility provider. A line may be destroyed. The homeowner should not attempt a repair like this. Allow the specialists to carry out their duties.

Honeywell Home RLV4305A1000 is a good choice if you need a replacement thermostat for the connectors, radiant ceiling, or baseboard heaters. The energy-saving individual temperature control and the simple two-wire installation make this an excellent choice for many people. Furthermore, you may preset several pre-programmed heating settings for different times of the day, night, weekends, and weekdays, among other things.

Frequently Asked Questions:

  • What is causing my thermostat to malfunction?

Your touchscreen thermostat may not be functioning correctly because the batteries need to be replaced, which is a simple solution. In contrast to a mechanical thermostat, a touchscreen thermostat requires batteries to operate. If your battery is the source of the problem, the thermostat will normally give you a warning before it shuts down.


Thermostats can go off for various reasons, including the need for fresh batteries or running out of gas. Normal noises are nothing to be concerned about, but if the clicking becomes constant or excessively frequent, you may have a problem with your hands. It’s simple to tell when something is much too cold or far too hot.

It is beneficial to pay close attention to those clicks. Your thermostat can assist you in lowering your electricity bills by alerting you when it is time to replace your insulation or even by increasing the temperature in the summer and decreasing it in the winter.
