What Are Common Reasons My Heater Is Not Working in My House?
Common heater failures usually come from simple issues. Check thermostat settings or dead batteries, a tripped breaker, a dirty air filter, or the furnace switch off. Other causes include igniter or flame sensor failure, pilot or gas supply problems (gas furnaces), safety lockouts, or a failed blower/control board. Try these first:
- Set Heat and raise 3–5°F.
- Replace thermostat batteries and the filter.
- Check the furnace switch and breaker. Bell offers same-day repairs and emergency HVAC service in Denver. Annual inspections help prevent breakdowns.
