<p dir="ltr" style="text-align:center"><em>How to fix Honeywell Thermostat heat not working on auto?</em></p>

<h3 dir="ltr" id="tag-53">Check All the Wires</h3>

<p dir="ltr">The first thing you should do is make sure your wiring is in good working order.</p>

<p dir="ltr">A wire may be too short or damaged. In any situation, you must inspect all of your wiring. </p>

<p dir="ltr">So, take the thermostat off the wall and inspect the wiring.</p>

<p dir="ltr">Check every single wire back there for any shorts or damage. </p>

<p dir="ltr">Also, twist the G, R, and W wires together to confirm nothing is amiss with them.</p>

<p dir="ltr" style="text-align:center"><em><img alt="" src="http://gospeedcheck.com/filemanager/data-images/imgs/20221025/honeywell-thermostat-heat-not-working-on-auto%20(6).png" style="height:689px; width:640px"></em></p>

<p dir="ltr" style="text-align:center"><em>Check All the Wires</em></p>

<p dir="ltr">If you believe there is nothing wrong with the wires—that everything is intact and appears good - you may need to get expert assistance to fix the issue.</p>

<h3 dir="ltr" id="tag-65">Restart/reset Thermostat</h3>

<p dir="ltr">A false alert might cause you to question whether or not your thermostat is operating properly. </p>

<p dir="ltr">As a result, the first thing you should do is reset your thermostat to see if it helps.</p>

<p dir="ltr">Troubleshooting before restarting your thermostat may be unnecessary, since everything might be addressed with a simple system reset.</p>

<p dir="ltr" style="text-align:center"><em><img alt="" src="http://gospeedcheck.com/filemanager/data-images/imgs/20221025/honeywell-thermostat-heat-not-working-on-auto%20(7).png" style="height:425px; width:640px"></em></p>

<p dir="ltr" style="text-align:center"><em>Restart/reset Thermostat</em></p>

<p dir="ltr">Here's how to manually restart your thermostat.</p>

<ul>
<li dir="ltr">
	<p dir="ltr">Make sure your thermostat's auto mode is turned off and the device is turned on. Switch the thermostat to the off position to turn it off.</p>
	</li>
	<li dir="ltr">
	<p dir="ltr">Locate and deactivate the breakers that power your HVAC system.</p>
	</li>
	<li dir="ltr">
	<p dir="ltr">Hold this position for around 30 seconds before turning on the breaker.</p>
	</li>
	<li dir="ltr">
	<p dir="ltr">Finally, switch on the thermostat and check to see whether the auto mode now works!</p>
	</li>
</ul>
<p dir="ltr">It is recommended that you reset your thermostat periodically in order to avoid unexpected power outages.</p>

<p dir="ltr">Notably, you can apply this method to solve the problem of <a href="https://gospeedcheck.com/article/nest-thermostat-blinking-green-when-charging-1088">Nest Thermostat blinking green when charging</a>.</p>

<h3 dir="ltr" id="tag-87">Turn on the heating</h3>

<p dir="ltr">If your Honeywell thermostat auto setting is inactive, you probably haven't selected the "heat" option in the thermostat's menu.</p>

<p dir="ltr">The "heat" option may be found in the thermostat's menu, where you select the auto settings.</p>

<p dir="ltr" style="text-align:center"><em><img alt="" src="http://gospeedcheck.com/filemanager/data-images/imgs/20221025/honeywell-thermostat-heat-not-working-on-auto%20(8).png" style="height:629px; width:640px"></em></p>

<p dir="ltr" style="text-align:center"><em>Turn on the heating</em></p>

<p>Keep in mind that the auto settings will activate the existing thermostat sets you've selected.</p>

<p dir="ltr">If you haven't selected to heat in the menu, the Honeywell thermostat not heating, it seems that the auto feature isn't operating.</p>

<h3 dir="ltr" id="tag-97">Program the Thermostat</h3>

<p dir="ltr">If your Honeywell thermostat is programmable, check sure it is set to the temperature you want it to function at.</p>

<p dir="ltr">You must have configured your thermostat to operate in "heating" mode at the correct time of day, or else the auto feature will not function properly.</p>

<p dir="ltr">Here's how to properly configure a Honeywell thermostat:</p>

<ul>
<li dir="ltr">
	<p dir="ltr">Step 1: Navigate to your thermostat's settings.</p>
	</li>
</ul>
<p dir="ltr" style="text-align:center"><img alt="" src="http://gospeedcheck.com/filemanager/data-images/imgs/20221025/honeywell-thermostat-heat-not-working-on-auto%20(9).png" style="height:431px; width:640px"></p>

<ul>
<li dir="ltr">
	<p dir="ltr">Step 2: Open the auto menu and navigate to the day configuration.</p>
	</li>
	<li dir="ltr">
	<p dir="ltr">Step 3: Set a certain time of day and select “<strong>heating</strong>”.</p>
	</li>
</ul>
<p dir="ltr" style="text-align:center"><img alt="" src="http://gospeedcheck.com/filemanager/data-images/imgs/20221025/honeywell-thermostat-heat-not-working-on-auto%20(10).png" style="height:447px; width:640px"></p>

<ul>
<li dir="ltr">
	<p dir="ltr">Step 4: Press the <strong>Set </strong>button to save the setup.</p>
	</li>
</ul>
<p dir="ltr">Your thermostat will now enable 'heating' automatically "mode, at the time you specify.</p>

<h3 dir="ltr" id="tag-119">Check auto settings and update</h3>

<p dir="ltr">If your thermostat's auto mode is somewhat unreal or does not cover your furnace's capability, the auto mode will most likely be disabled.</p>

<p dir="ltr">The thing you should do here is make sure that the auto performance settings you specified fit the requirements of the remainder of your system.</p>

<p dir="ltr">In other words, before turning on the thermostat on auto again, double-check the settings.</p>

<p dir="ltr" style="text-align:center"><em><img alt="" src="http://gospeedcheck.com/filemanager/data-images/imgs/20221025/honeywell-thermostat-heat-not-working-on-auto%20(11).png" style="height:480px; width:640px"></em></p>

<p dir="ltr" style="text-align:center"><em>Check auto settings and update</em></p>

<p dir="ltr">If you've made any changes, make sure to restore them to their original state and test the auto settings again.</p>

<p dir="ltr">Furthermore, look for the correct settings configuration for your thermostat model and align them to eliminate the likelihood of a defective thermostat.</p>

<blockquote>
<p dir="ltr"><strong>Note</strong>: Keep in mind that if your thermostat software is out of current, you may encounter malfunctions.</p>
</blockquote>

<p dir="ltr">Look for an Update tab and any pending updates in your thermostat's menu.</p>

<h3 dir="ltr" id="tag-134">Factory default</h3>

<p dir="ltr">If the thermostat's auto setting is still not working, it's necessary to take more serious actions. </p>

<p dir="ltr">The so-called factory reset will return your device to the state it was in when it was first opened.</p>

<p dir="ltr">All settings and setups will be lost indefinitely.</p>

<p dir="ltr">Here's how to reset your thermostat to factory settings:</p>

<ul>
<li dir="ltr">
	<p dir="ltr">Look for the reset button on the panel.</p>
	</li>
	<li dir="ltr">
	<p dir="ltr">For at least 10 seconds, press and hold the reset button.</p>
	</li>
</ul>
<p dir="ltr">This process should return your thermostat to its default settings, and the auto-settings should function normally.</p>

<p dir="ltr" style="text-align:center"><em><img alt="" src="http://gospeedcheck.com/filemanager/data-images/imgs/20221025/honeywell-thermostat-heat-not-working-on-auto%20(12).png" style="height:360px; width:640px"></em></p>

<p dir="ltr" style="text-align:center"><em>Factory default</em></p>

<h3 dir="ltr" id="tag-150">Inspect limit control</h3>

<p dir="ltr">If the problem hasn't been resolved by now, there's an easy technique to figure out which part is preventing the automatic heating.</p>

<p dir="ltr">You will now witness each step of the process in operation and will know what to replace based on what does not start.</p>

<p dir="ltr">Extremely careful with the instructions and avoid touching any wires, as you may be electrocuted.</p>

<p dir="ltr">Also, avoid touching or twisting the round dial.</p>

<p dir="ltr">Here's way to figure out which portion isn't working:</p>

<ul>
<li dir="ltr">
	<p dir="ltr">To access the controls, open the front furnace door</p>
	</li>
	<li dir="ltr">
	<p dir="ltr">Find the fan limit switch (usually at the bottom left corner and fashioned like a white cylindrical button)</p>
	</li>
	<li dir="ltr">
	<p dir="ltr">Turn the heat up to high</p>
	</li>
	<li dir="ltr">
	<p dir="ltr">The burner should start</p>
	</li>
	<li dir="ltr">
	<p dir="ltr">The limit control dial should begin to rotate</p>
	</li>
	<li dir="ltr">
	<p dir="ltr">The blower should turn on</p>
	</li>
</ul>
<p dir="ltr" style="text-align:center"><em><img alt="" src="http://gospeedcheck.com/filemanager/data-images/imgs/20221025/honeywell-thermostat-heat-not-working-on-auto%20(13).png" style="height:425px; width:640px"></em></p>

<p dir="ltr" style="text-align:center"><em>Inspect limit control</em></p>

<p dir="ltr">If only the AUTO function is not working, the blower will most likely not start, indicating a problem with the temperature sensor.</p>

<p dir="ltr">If you can confirm that by personally inspecting the controls, you'll need to bring the thermostat in for repair.</p>

<h3 dir="ltr" id="tag-176">Replace your Thermostat if it’s faulty</h3>

<p dir="ltr">Though it might be difficult to accept, the reason your Honeywell thermostats aren't working on auto is because the thermostat is defective and has to be replaced. </p>

<p dir="ltr">If the techniques outlined above were ineffective in repairing your thermostat, it might be time to replace it.</p>

<p dir="ltr" style="text-align:center"><em><img alt="" src="http://gospeedcheck.com/filemanager/data-images/imgs/20221025/honeywell-thermostat-heat-not-working-on-auto%20(14).png" style="height:480px; width:640px"></em></p>

<p dir="ltr" style="text-align:center"><em>Replace your thermostat </em></p>

<p dir="ltr">Get a new one or a newer one (if your current model is obsolete) to experience all of the amazing features the thermostat has to offer, such as automatic temperature management.</p>

<h3 dir="ltr" id="tag-185">Contact Honeywell Support Team or an HVAC professional</h3>

<p dir="ltr">Assuming the problem is not caused by the wires, the next step is to contact the <strong><a href="https://www.honeywell.com/us/en/contact">Honeywell support</a></strong> team. </p>

<p dir="ltr">Honeywell has plenty of seasoned personnel that deal with situations like these all day.</p>

<p dir="ltr">However, while dealing with a representative, make sure you cover all aspects of the problem. </p>

<p dir="ltr">This will assist them in determining what steps to take to restore your thermostat's functionality.</p>

<p dir="ltr">On the one hand, you may wish to contact a local HVAC specialist to address the problem as soon as possible. </p>

<p dir="ltr">As previously said, an HVAC specialist would examine the entire thermostat (including the furnace) to determine what went wrong.</p>
