It could be displaying an inaccurate temperature. In this case, your car may not be overheating, but your temperature gauge won't be able to warn you. Thermostats can often go bad after about 10 years of use.
Yes, but not for very long. Thermostats typically ``fail closed,'' which means your coolant won't circulate and you'll overheat very quickly. I wouldn't - even removing the thermostat is better than leaving a failed thermostat in place (it will take longer to warm up, but it won't overheat on you!)
The Lifespan of a Thermostat
On average, most thermostats last about 10 years, depending on the model, usage, and proper maintenance. However, many people decide to replace their unit sooner to take advantage of new energy-saving technologies.
If the AC unit or furnace constantly runs and doesn't turn off when the desired temperature is reached, the wiring within the thermostat may be failing. It can also be a sign of miscalibration, which causes the thermostat to send the incorrect signals to the air conditioner, furnace, or heat pump.
The cost to install a thermostat is $182 on average, but you could pay between $113 and $264. Thermostats play an important role in our daily lives, cooling us down during the sweltering summer heat and keeping us warm and cozy during winter. While the average cost to install a thermostat is $182, pricing can vary.
One easy thing you can do to check the accuracy of your thermostat is to do a temperature check. See what your thermostat reads. Then use a portable indoor thermometer to compare the temps. Another good way to do the temperature check is to download one of the many free apps that allow you to check indoor temperatures.
In most cases, installing a new thermostat is a relatively simple do-it-yourself project that can result in improved comfort and convenience and one that can help you save energy.
While there is a small chance that there is an issue with the running temperature of your engine, by far the most common issue with trouble code P0128 is a faulty thermostat. The exact location of the thermostat and issues related to a damaged thermostat may vary depending on your vehicle.
This can happen if there is a power surge or if the thermostat is connected to a faulty electrical circuit.
You Notice Erratic Temperature Changes
If you notice sudden and erratic temperature changes from cold to hot or hot to cold, then it could be a sign that your thermostat has stopped working correctly. Get your vehicle inspected if you notice these extreme temperature changes in your vehicle interior.
Car thermostat replacement time is 30 to 60 minutes, depending on the make of the car. It will cost you around $190 to $350, including labor. Thermostat repairs usually take more time, requiring extra time to diagnose and analyze the vehicle's thermostat. It can take up to 2 hours.
You might have a stuck thermostat or a water pump that's failed. You could also have a cooling fan that isn't working depending on how fast you were going when it overheated.
Luckily, it only takes a few minutes and a couple of tools to change your thermostat yourself. Our guide will show you how to remove the bad thermostat and replace it with a new one!
If your thermostat has fresh batteries but suddenly lacks power, flashes, or isn't responsive to adjustments, it may need replacement. If resetting the thermostat doesn't resolve the problem, you may have wiring problems or faulty components causing your thermostat to not turn on.
Moving a Thermostat: If the required wiring exists at the desired location, moving a thermostat may cost as little as $65. However, moving the unit can entail installing new wiring and cutting and patching drywall, so the project can cost up to $450.
Signs of a Bad Thermostat
If there's no change in your home's temperature when you adjust the temperature, or the display is unlit or unresponsive, your thermostat may be broken, or the batteries need replacing.
Signs that You Need to Replace Your Thermostat
Your HVAC system keeps cycling on and off irregularly. Registering wrong temperatures. High energy bills. Inconsistent temperatures through the house.
Installation typically takes about 1 hour.
If you drive with a bad thermostat, your car could overheat, causing severe and expensive engine damage. And while it's technically possible to drive without a thermostat, we don't recommend it. Your car will not reach an acceptable operating temperature, resulting in higher fuel consumption and excessive engine wear.
You can typically just replace the outdated thermostat with a new thermostat – assuming the latter is compatible with your HVAC system. There are a few things you should know, however, when upgrading your thermostat.
