- Use a gas detector to check for leaks.
Never attempt repairs if you smell gas. Evacuate and call a professional immediately. Handling gas safely can prevent explosions and poisoning.
Remember to wear safety gear, including gloves and goggles. Keep a fire extinguisher nearby for emergencies.
Checking Thermostat
Checking your thermostat is crucial for Tempstar furnace troubleshooting. The thermostat controls your furnace’s temperature settings. Ensure it is functioning correctly.
Settings Verification
First, verify the thermostat settings. Make sure the thermostat is set to heat. Check the temperature setting. It should be higher than the current room temperature.
- Set to heat mode.
- Temperature set above room temperature.
Switch the fan setting to auto or on. This ensures the fan works correctly.
| Mode | Description |
|---|---|
| Auto | Fan runs only when heating. |
| On | Fan runs continuously. |
Battery Replacement
Some thermostats use batteries. Check if the batteries are still good. Replace the batteries if needed.
- Remove the thermostat cover.
- Take out the old batteries.
- Insert new batteries.
- Replace the cover.
Use fresh, high-quality batteries. This ensures optimal performance. Check the battery orientation before inserting.
If the thermostat still doesn’t work, contact a technician. Professional help may be needed.
Inspecting Filters
Inspecting the filters of your Tempstar furnace is crucial. Clean filters ensure efficient operation. Dirty filters can cause many issues. They can reduce airflow and efficiency. Regular inspection and maintenance are vital for peak performance.
Filter Removal
First, turn off the furnace. Locate the filter compartment. This is usually near the air intake. Open the compartment carefully. Pull out the filter slowly. Be gentle to avoid damage. Note the filter’s position for reinstallation.
Cleaning Or Replacement
Check the filter’s condition. If it’s reusable, clean it. Tap it gently to remove loose debris. Use a vacuum for thorough cleaning. If the filter is damaged or very dirty, replace it. Choose the correct size for your furnace. Insert the new or cleaned filter in the correct position. Close the compartment securely.
Examining Pilot Light
Understanding the pilot light in your Tempstar furnace is crucial. A malfunctioning pilot light can disrupt your furnace’s operation. This section will guide you through checking and relighting the pilot light.
Pilot Light Status
First, check if the pilot light is on. Locate the pilot light assembly near the furnace’s burner. A functioning pilot light should display a steady blue flame.
| Pilot Light Color | Status |
|---|---|
| Blue | Normal Operation |
| Yellow or Red | Needs Attention |
| Off | Relighting Required |
Relighting Instructions
If the pilot light is off, follow these steps to relight it:
- Turn off the furnace and wait for it to cool.
- Find the gas valve and set it to the “Off” position.
- Wait five minutes to clear any gas.
- Turn the gas valve to the “Pilot” setting.
- Hold a lit match to the pilot opening.
- Press the reset button on the control panel.
- Keep the button pressed for 30 seconds after the pilot lights.
