If these steps don’t solve the issue, there might be a deeper electrical problem. Contact a professional to inspect your system.
Checking The Thermostat
When your heating doesn’t come on after turning up the thermostat, the issue might be with the thermostat itself. This is an easy and quick step to check before calling a professional. We will guide you through some simple checks to ensure your thermostat is working properly.
Battery Replacement
Begin by checking the thermostat’s batteries. Old batteries can cause the thermostat to malfunction. Open the thermostat cover and locate the batteries. Replace them with fresh ones. Make sure to use the correct type of batteries as specified in the manual.
Settings Verification
After replacing the batteries, check the thermostat settings. Ensure the device is set to “heat.” Sometimes, it might be accidentally set to “cool” or “off.” Also, verify the temperature setting. It should be higher than the current room temperature for the heating to start.
Look for any programming errors. If the thermostat has a schedule function, make sure the current time and date are correct. Incorrect settings can prevent the heating system from turning on.
Inspecting Power Sources
When your heating system refuses to turn on, it’s frustrating. Often, the issue lies with the power sources. Let’s dive into some steps to inspect these power sources. This helps you identify and fix the problem quickly. Follow these simple steps to check your heating system’s power sources.
Circuit Breaker Check
First, locate your home’s circuit breaker panel. It’s usually in the basement, garage, or utility room. Open the panel door and look for any tripped breakers. If a breaker is tripped, it will be in the middle position. Reset it by turning it off, then back on. This may restore power to your heating system. If the breaker trips again, there might be a deeper issue. You should contact a professional for further inspection.
Fuse Inspection
Next, check the fuses related to your heating system. Fuses are often in older homes. They are usually found near the circuit breaker panel. Look for any blown fuses. A blown fuse will have a broken metal filament inside. Replace it with a fuse of the same type and rating. Ensure the new fuse fits snugly. This should restore power to your heating system. If the fuse blows again, there might be an underlying problem. Seek help from a qualified technician.

Examining The Furnace
When the heating does not come on after turning up the thermostat, the problem might lie in the furnace. Checking the furnace involves a few critical steps. Each step can help pinpoint the issue. Let’s delve into these steps and ensure your furnace is in good working order.
Pilot Light Status
The pilot light is essential for your furnace to work. If the pilot light is out, the furnace will not ignite. Check if the pilot light is burning. If it is off, relight it following the furnace manual’s instructions.
- Locate the pilot light assembly.
- Turn the gas valve to the “Off” position.
- Wait a few minutes for any gas to clear.
- Turn the valve to “Pilot” and hold a lit match to the pilot opening.
- Press the reset button until the pilot light stays lit.
Make sure to check if the pilot light remains steady. If it goes out again, there might be a draft or an issue with the thermocouple.
Gas Valve Position
The gas valve controls the flow of gas to the furnace. If the valve is not in the correct position, the furnace will not receive fuel to ignite.
Ensure the gas valve is in the “On” position. It should be parallel to the gas line. If the valve is perpendicular, turn it to align with the pipe.
Sometimes, the gas valve gets accidentally turned off. This is an easy fix but essential for the furnace to operate correctly.
| Component | Status | Action |
|---|---|---|
| Pilot Light | Off | Relight following manual |
| Gas Valve | Off | Turn to “On” position |
