Other Costs Associated with Furnace Repair

To understand the other costs associated with furnace repair, let me tell you about the control board, blower motor, gas valve, and flame sensor replacements that may be required. 

Each component plays a crucial role in the process, and a faulty part can result in a damaged HVAC system and even pose a safety hazard. 

Control Board Replacement

As your furnace gets older, certain parts may need replacing. A popular one is the control board – a small, vital piece of equipment for controlling and monitoring your furnace. 

Here’s a 6-step guide on how to do it:

  1. Switch off furnace power
  2. Remove furnace panels
  3. Find the control board, near the blower motor
  4. Detach any wires or cables from the existing control board
  5. Attach the new control board and reconnect all cables
  6. Put back the panels and restore furnace power

Blower Motor Replacement

Replacing a blower motor is a common furnace repair. It is responsible for pushing warm air from the furnace to the home. 

Without it, there is no heat in the living space. To replace it, follow these steps:

  1. Switch off the breaker controlling the furnace.
  2. Loosen and remove bolts/screws, then take off the motor assembly.
  3. Detach wires and capacitor from the old motor and remove it from its bracket.
  4. Attach the wires and capacitor to the new motor. Then attach it to the bracket and fasten bolts/screws.
  5. Turn on the power and test the new motor.

Gas Valve Replacement

Gas valve replacement is an essential part of furnace repair. It regulates the flow of gas into the unit. 

Here’s a guide to help you understand the process:

  1. Turn off the gas supply line. Safety comes first!
  2. Disconnect and remove the old valve with a wrench or pliers.
  3. Install the new valve, reconnect wires/connectors, and turn on the gas supply line.

Flame Sensor Replacement

To replace a flame sensor, these are three steps to follow:

  1. Turn off the power supply to the furnace. Disconnect wires from the sensor carefully, using a nut driver. Then, take out the flame sensor.
  2. Clean the sensor with a steel wool pad. Do it gently to avoid damage.
  3. Finally, place the cleaned or new flame sensor back in its place. Reattach the wire connections and switch on the power supply to check if it works.

Home Warranty Coverage for Furnace Ignitor Replacement

To navigate the complex world of furnace repair, you need to consider insurance options that meet your needs. 

A home warranty is a contract you can buy to protect your household appliances and systems. You pay an annual premium and in return, the warranty provider will cover repair or replacement costs if they break down due to normal wear and tear.

Furnace ignitors are important for heating systems. They produce sparks which light up the burners. Many home warranties cover furnace ignitor replacements, but not if caused by neglect or improper maintenance. However, some plans may require customers to call during business hours for emergency repairs.

Different levels of coverage are available depending on the plan chosen. Some may only cover systems, while others may cover appliances too. Consumer Reports says around 20% of US households have bought a home warranty. It’s important to do research and understand what your policy covers.

Does a Home Warranty Cover Furnace Ignitor Replacement?

Some home warranty providers offer coverage, while others may not. If your plan does cover it, you can expect some or all of the repair/replacement costs to be covered. 

However, there may be limits and exclusions based on factors such as age and condition of your heating system. 

It’s essential to read your policy docs carefully to understand what is/isn’t covered. If you’re considering a home warranty plan or need to file a claim, consult customer service or a rep from the provider.
