Fixes For Williams Wall Heater Not Turning On

Your heater might work fine for some time but then suddenly stop working and refuse to turn on. There are several causes for this problem, some of which can be resolved without contacting a professional HVAC specialist. In certain circumstances, troubleshooting might get your furnace or heat pump running again without needing a repair call.

These troubleshooting steps will assist you in repairing issues that may be the root of this problem.

Clogged Flame Sensor

A furnace flame sensor recognizes the presence of a flame as the gas passes through the system. Suppose it becomes clogged by dust from burning. In that case, it may not accurately recognize the flame and is improperly forced to close the furnace for safety, even if everything else is operating perfectly.

Follow these troubleshooting methods to clean the flame sensor:

  1. Turn off the power and the gas to the furnace.
  2. Take off the access panel.
  3. Locate a flame sensor and use a 14-inch hex wrench to detach it. Slide it out carefully. You may have to remove the wire to have greater access.
  4. Gently scrape the flame sensor rod with light grain sandpaper to clean carbon and soot.
  5. Wipe the sensor clean with a clean towel.
  6. If required, reconnect the wires and reconnect the flame sensor.
  7. Reinstall the access panel and reconnect the gas and electrical power.

Clogged Air Filter

A clogged air filter may cause the temperature inside of the furnace to increase to dangerous levels. If this occurs, the furnace shuts down to protect components such as the heat exchanger and other equipment. Examine the filter and replace it if necessary.

Thermostat Problem

In most cases, the thermostat is in charge of controlling the heating unit. As a result, you must evaluate the Williams wall furnace thermostat to establish whether the problem is with the thermostat's power. Examine the thermostat's display. It could be a power issue if turned on, but the screen is black.

Some thermostats include batteries, so try replacing the batteries. Check the house circuit breaker box as well. Check if the breaker controlling the electricity towards the thermostat has not malfunctioned. If necessary, you will need to reset it.

Resetting The Electric Heating System

Here are the steps to follow when resetting your electric heating system:

  1. Switch off the electricity by flipping the breaker in the circuit box.
  2. Find and push the reset button on the heater. It is typically situated near the blower motor inside the blower area. Be cautious since it may be hot.
  3. Press the button if you have already found it.
  4. Return the cover to the blower area and switch on the electricity.

Wrong Thermostat Settings

The heater will not turn on when you set the thermostat incorrectly. Ensure that the thermostat is set to "Heat," and the average temperature should be a few times hotter than the room temperature.

No Power To Furnace

Since all furnaces demand electricity and gas furnaces require natural gas utility supplies, your furnace or heater will not operate without power or fuel. As a result, you must determine if the system has power or gasoline.

  1. Examine the circuit box. Check that the breaker that controls the power to your unit is not damaged and that the air handler does not cause malfunction.
  2. Reset the circuit if the air handler has broken. Check the manual on/off switches on your device to make sure that they have not been mistakenly flipped.
  3. Examine the furnace for a blown fuse, and replace it if necessary. 

Loose Access Door

Many heating system types include a safety mechanism that prevents them from operating if the access panels are not secured. It prevents accidents and internal component damage.

What To Do When Your William Wall Heater Does Not Ignite

The Williams wall furnace pilot light will not stay illuminated due to an obstruction in the pilot tube. As a result, you must deactivate the gas, clean the pipe with an air compressor, and relight the pilot. If it does not work, you must contact a maintenance specialist or replace the thermocouple.

Dirty Electronic Ignition

If the furnace is reluctant to ignite at startup, it might be due to carbon deposits, which you can remove by spraying the ignitor probe with compressed gas. Compressed air cans come with long straw-like applicators, and if you tip the applicator straight at the probe, the blast of air may do the work.

If your furnace has a spark ignitor performing erratically, it may be coated with soot, and a burst of compressed air could be enough to clear it.

What If Your Furnace Shuts Down And Does Not Turn On Again?

If the furnace is not turning on, check to see if the filter is clean. Filters that are clogged reduce airflow and might hinder the furnace from operating. Additional reasons it won't start include incorrect thermostat settings, not turning on the gas line, or defective pilot light.

Dirty Air Filter

If you don't change your filters regularly, your vents and registers could be entirely blocked. This will affect the proper airflow of your furnace. First, ensure that the furnace filter is clean and recently replaced, then verify that any vent registers are free of clogs and dirt.

Dirty Flame Sensor

The flame sensor is one of the common issues whenever your furnace doesn't want to ignite. If you hear a click on your furnace and it doesn't light up, this is usually the problem. To resolve this issue, here are the steps:

  1. Turn off the furnace.
  2. Close the gas valve.
  3. Take out the furnace flame sensor.
  4. Using an emery cloth, clean the sensor.
  5. Replace the flame sensor.
  6. Start the furnace again.
