No Heat Checklist


No Heat Checklist from Charlie the DogNo Heat on your oil fired furnace? Here are a few things to check:

  1. Check your thermostat to make sure it’s set to heat and set high enough to call for heat, meaning the desired temperature is higher than the room temperature. Also make sure if your thermostate requires batteries, the batteries are good.
  2. Make sure you have oil in your tank. Do NOT always trust your gauge, they can be finicky.
  3. Locate the emergency shutoff switch, usually located near the basement steps and/or next to your heating system. Make sure the switch is in the "ON" position. These switches look just like a light switch and accidentally get turned off if you have guests in your home. This happens more frequently than you might think.
  4. Check for any blown fuses or tripped circuit breakers in your electrical box.
  5. Sometimes a simple system reset is all that’s needed. Locate your heating system’s burner and press the reset button ONCE (and only ONCE) and listen for the system to start up. If you had to open a door to access your furnace be sure to close that door after pressing the reset button.

If you have an emergency call Hillside at 302-738-4144 or 410-398-2146.
