To check if your programmable heater is functioning correctly, ensure it is set to the desired temperature, listen for operational sounds, and monitor if it heats up adequately.
A programmable heater should keep your home warm efficiently. But how do you know if it’s working right? This guide shows you how to test your heater’s key functions.
Basic Function Checks
Start with these simple tests to verify your heater’s core functions.
Power Verification
Check if the unit has power:
- Look for indicator lights or display
- Listen for fan or heating sounds
- Test outlet with another device
Thermostat Accuracy Test
Compare thermostat reading to actual room temperature:
- Place a thermometer near the thermostat
- Wait 15 minutes for temperatures to stabilize
- Check for differences greater than 2°F
Advanced Performance Tests
These tests help identify deeper issues with your heating system.
Heat Output Measurement
Measure temperature rise across the heater:
| Location | Expected Temp Rise |
|---|---|
| Air intake | Baseline |
| Air output | 15-25°F higher |
Cycle Duration Check
Proper heaters should run complete cycles:
- Normal cycle: 10-15 minutes
- Short cycling indicates problems
- Continuous running suggests thermostat issues
