When Should I Replace My Thermostat?

When Should I Replace My Thermostat?

Thermostat serves as a watchdog in keeping the preferred temperature for your home.  However, no matter how much you care for it, thermostats also don’t last a lifetime. Here are the most common signs that you need a thermostat replacement NOW.

Leakage from the mounting surface

This is usually caused by improper thermostat installation or when your technician used a low-class and ineffective sealant or gaskets. This is probably the reason why you notice large coolant breed marks around the housing of your thermostat.

To prevent this kind of incident, be sure to follow the installation guide and hire only a professional technician to install your thermostat. If it requires a new sealant, clear first the mounting before applying a new one. However, if the leakage is not caused by these two, then you need to replace your thermostat immediately.

Noticeable rust and corrosion

Corrosion’s are mostly caused by contaminated and non-compatible coolants. However, in some cases, a defective pressure cap may be to blame. It produces air bubbles that trigger rust and corrosion.

Replacing your thermostat is necessary, but before installing the new device, be sure to flush the cooling system and have it filled with a compatible and manufacturer’s recommended coolant. Replace defective pressure cap as well.

Deposit Build-up

Deposit and sludge buildup inside the thermostat can clog and hinder its proper operation. This is usually caused by contaminated coolants or if different types of coolants are mixed together. Sometimes, dirt and dust also clog the inside and cause parts to malfunction.

Before replacing your thermostat, see to it that you clear the coolant system and fill it with coolants, which the manufacturer recommends. Be sure to clean your thermostat regularly.

Erratic change in temperature

Another common indication of a failing thermostat is the unusual spike and drop in temperature, which can greatly affect its components and performance.

It can also lead to higher energy bills and insufficient cooling. If you notice that the temperature is strangely low then shortly climbs to an abnormally high level, then it’s time to have your thermostat checked or replaced.
