Furnace: Malfunctioning Thermostat?

If you're experiencing issues with your furnace, a malfunctioning thermostat might be the culprit. Here's how to identify the problem and address it:


Signs of a Malfunctioning Thermostat

  1. Temperature Discrepancies: The room feels colder or hotter than the thermostat's settings.
  2. Frequent Cycling: The furnace turns on and off too frequently, or not at all.
  3. Unresponsive Thermostat: The display is blank, or the unit doesn't respond to adjustments.
  4. Incorrect Readings: The temperature displayed on the thermostat doesn’t match the actual room temperature.

Common Causes

  1. Dead Batteries: For battery-powered thermostats, this is often an easy fix.
  2. Dirt or Debris: Dust can interfere with sensors or electrical connections.
  3. Loose Wiring: Wires inside the thermostat can loosen over time, disrupting communication with the furnace.
  4. Outdated Model: Older thermostats may fail to regulate modern furnaces efficiently.

Troubleshooting Steps

  1. Check Power: Ensure the thermostat has power. Replace batteries or check circuit breakers if necessary.
  2. Clean the Unit: Remove the cover and gently clean any dirt or debris with a soft brush.
  3. Verify Settings: Ensure the thermostat is set to "Heat" and the temperature is above the current room temperature.
  4. Inspect Wiring: Check for loose or frayed wires, but only if you're comfortable doing so.

When to Call a Professional

If troubleshooting doesn’t resolve the issue, a professional HVAC technician can:


  • Test the thermostat for defects.
  • Check furnace compatibility with the thermostat.
  • Install a new, energy-efficient model if needed.

Upgrading to a programmable or smart thermostat could also improve efficiency and comfort in your home.

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!

by Trevor Owens on Twintech Heating and Cooling

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. I’ve used the company in the past for my furnace so I was happy when I recognized Greg at my front door. He’s great and the service is always top notch. I’d highly recommend using twintech for honest, superior service in the Durham region. Thanks!

by Nicole Alain on Twintech Heating and Cooling

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!

Twintech Heating & Cooling installed my furnace in 2022 and in fall of 2023 installed my Panasonic Heat Pump. Greg and Mitch did a great job. Helped me through the rebate process. Super happy with the Heat Pump. Only used my furnace 5 times this winter. Energy bills lower, carbon emissions lower.Thank you Twintech. I recommend highly!
