Williams Wall Heater Constantly Turning Off: Why And How To Deal With It?

Are you trying to figure out why your Williams wall heater keeps shutting off? You’re on the right page, then!

Airflow obstruction is the major cause of your Williams wall heater’s intermittent shutoff. However, a broken thermostat can also be at blame.

We’ll go into more detail about what stops the airflow from flowing and how to identify and fix a broken thermostat in the sections that follow. We’ll also discuss some more issues that could arise with your Williams wall heater and how to resolve them.

What Results In The Obstruction Of Airflow In Wall Heaters?

When you think this might be the problem, see if any nearby objects, such as curtains, furniture, or plants, are blocking the heater’s airflow. Check to see if your gadget is now operating properly after removing these impediments immediately.

If the issue still exists, a dirty air filter can be to blame. As a result, the internal temperature of your unit will increase. When it occurs, the Williams heater immediately switches off to prevent damage to other components, such the heat exchanger. You must thus inspect the air filter and change it as necessary.

How Can A Faulty Thermostat Be Diagnosed?

Here are some indicators to look out for to determine if you have a broken thermostat:

The most obvious sign that anything might be amiss with your thermostat is when it either has no electricity or is unresponsive. If the temperature in your home doesn’t change when you adjust the thermostat, or if the display is dim or unresponsive, you may be dealing with a faulty thermostat.

The thermostat is broken if it cannot properly tell the HVAC system when to turn on or off. Your HVAC system may not receive electrical signals from the thermostat due to a wiring defect, such as:

  • tattered wires
  • insufficiently calibrated settings
  • defective wiring
  • zero power

There will occasionally be small temperature variations across rooms, but if there are persistently substantial variations, the thermostat may be broken.

A programmable thermostat is designed to remember your schedule and preferences for a long time. You shouldn’t have your settings “forgotten” unless you decide to alter them. As a result, the thermostat may need to be replaced if it routinely deviates from your plan because it is growing unreliable.

Call your go-to HVAC expert right away to have your thermostat fixed if you know for sure that it is broken.

How Can A Malfunctioning Williams Heater Thermostat Be Fixed?

Your thermostat may occasionally stop working if your batteries are poor. So, if you discover that’s what created the issue, think about checking and replacing them.

Additionally, check the circuit breaker box in the house. Verify that the breaker that regulates the power to the thermostat has not tripped. You’ll have to reset it if necessary.

On occasion, the thermostat may be set incorrectly, preventing your heating system from going on. Make sure the temperature is a few degrees higher than the room temperature and that the thermostat is set to “Heat.” Make sure the set parameters are suitable for the time of year and the family’s routine.

Keep in mind that setting your thermostat to direct sunlight will cause your home’s temperature to be lower than you intended. You’ll obtain readings that overestimate the temperature if this is the case. Either your heating won’t turn on or it just stops. Put the thermostat in a cool, dark area away from the sun.

What Other Common Issues Might Your Williams Wall Heater Present?

Williams Wall Heater Constantly Turning Off: Why And How To Deal With It?

In this section, we’ll discuss some typical issues that you might run into with your Williams wall heater and how to remedy them.

Not Heating
A gas wall heater that won’t heat up is typically the result of a faulty pilot light.

These heaters function similarly to a gas water heater by having a pilot light that continuously fires and ignites the burner when the temperature goes below a set point.

Others, such as many more contemporary gas ovens, feature an electric igniter that uses a spark to light the burner.

You can do the following to repair it:

  • Check to see if there is adequate gas going to the heater. Check to see if the gas line valve is open or the tank is empty.
  • If you see that gas is flowing but the pilot is still off, there must be a blockage. To clean the tube, reach into the combustion chamber and blow some compressed air through it.
  • After turning off the gas, wait 10 minutes before attempting to relight the pilot. Any gas that could have remained in the combustion chamber will have had enough time to escape by the end of this period.

Unreliable Flame Sensor
This component, which frequently bears the name thermocouple, comes in direct touch with the pilot flame. This also serves as a safety valve that shuts off the gas supply to put out the pilot flame. Additionally, this gadget safeguards your house against a harmful gas accumulation.

This part may stop working due to dirt, damage, or misalignment.

Cleaning a defective furnace filter can be done by following these steps:

  • Turn off the main power supply, typically by its designated circuit breaker.
  • You must also shut off the gas to the heater unless the gas valve is electronically controlled.
  • Carefully remove the sensor; in some circumstances, it might be necessary to clear a space for yourself to work in by cutting the cord that is attached to the sensor’s end.
  • Use a gentle pad or a ball of steel wool to clean the flame sensor rod. Sandpaper shouldn’t be used to clean it because it will harm the flame rod.
  • After that, use a fresh paper towel to remove any remaining dust.
  • After cleaning the sensor, replace it with the combustor assembly, reconnect any damaged wires, and then switch the power back on.
  • Make sure the gadget is turned on again and is running properly until the thermostat is pleased before assuming you have fixed the problem.

The Heater Suddenly Stopped Working
When this occurs, check to see if a fuse has blown or a breaker has tripped. If necessary, replace the blown fuse and reset the breaker.

However, faulty wiring connections might occasionally be the culprit as well.

Remove the heater’s connection from the power source and disconnect it from the wall to inspect. Next, check the electrical components’ connections. You need to take off the faceplate, control, and thermostat knobs in order to do this. If you notice any loose wires, tighten them up.

Heating Fan Problems
There are two possibilities that could apply to this issue:

  • Although the heater fan runs, no heat is produced; or
  • Although there is heat production, the fan is not working.

Heater Fan Runs, But No Heat Is Produced
This can be the result of a broken heating element or shoddy wiring inside the appliance. It is necessary for you to:

  • Before removing the thermostat, control knob, and faceplate to check all of the electrical connections inside, turn off the unit’s power.
  • Any loose or broken connections should be tightened.
  • If it doesn’t function, the heater may need its element replaced.

To replace your heating element, speak with your reliable HVAC professional.

Although It Is Hot, The Fan Is Broken
Despite the heater heating up, the fan could stop working for a number of reasons. How to identify and resolve this issue is as follows:

  • Turn off the heater’s power before opening it to check the fan motor’s electrical connections.
  • Tighten any frayed or disconnected cables to the fan motor.
  • Make sure nothing is obstructing the fan blades.
  • A new fan motor is likely required if the fan still won’t work.

Heater Will Not Turn Off
The heater’s capacity may not be sufficient to heat the space, or the space may not be adequately insulated, as the cause of this issue.

This issue can be resolved fairly easily. To meet the room’s heating needs, you can either add another heater or replace your current heater with one that has a bigger capacity.

If insulation is the issue, you must insulate your walls and weatherstrip your doors and windows.

How Frequently Should You Have Your Wall Heater Serviced And Maintained?

Every year, it’s important to ensure that your heater is in top shape before the winter weather arrives. Here is a quick guide on how frequently your heater needs to be inspected:

  • To ensure that your heater will function effectively whenever you need it, you should get it inspected once or twice a year. This is essential in regions that frequently see yearly winter storms and snowfall of several feet to several inches.
  • When you reside in a location with mild winters, you should have a furnace, gas heater, and boiler inspected and maintained annually. By doing this, you can ensure that your heater is in good shape and ready to turn on again.
  • Regardless of whether it initially seems required, you should schedule a service maintenance every two to five years in hotter climes or regions without winter.


Check to see if there is anything blocking the airflow of your Williams heater, such as plants, papers, furniture, or curtains, before continuing. This is one of the primary causes of this, despite how straightforward it may seem.

Check your thermostat if you have already verified that the airflow is unobstructed. It could be broken.
