Ignition Failures
American Standard furnaces are reliable, but sometimes they face ignition failures. This issue can disrupt your home’s comfort. Understanding common ignition problems can help you troubleshoot effectively. Let’s focus on two common issues: pilot light and electronic ignition problems.
Pilot Light Issues
Pilot lights can sometimes go out. This can be due to a clogged orifice. Dirt and debris can block gas flow. Clean the pilot orifice gently. Use a needle or compressed air. Ensure the gas valve is open. Check the thermocouple. It’s a safety device that senses heat. If the thermocouple is faulty, it won’t keep the pilot lit. Replace it if needed.
Electronic Ignition Problems
Electronic ignitions are modern and efficient. But they can fail too. A common issue is a faulty ignition control module. This module sends a signal to ignite the burner. If it fails, the furnace won’t light. Check for error codes. These codes can guide you to the problem. Another issue could be the ignitor itself. Over time, the ignitor can crack. A cracked ignitor won’t spark. Inspect it visually and replace if needed.
Blower Motor Issues
Blower motor issues can cause your American Standard furnace to malfunction. Understanding these problems helps you maintain your furnace effectively. Here, we will discuss common blower motor issues such as a blower not running and a noisy blower.
Blower Not Running
If your blower motor is not running, it could be due to various reasons. Check if the thermostat is set correctly. Ensure the furnace switch is in the “on” position. Inspect the circuit breaker to see if it has tripped. Reset it if needed. Another reason could be a blown fuse. Replace the fuse to fix the issue. Sometimes, the blower motor itself might be faulty. In that case, you may need to replace the motor.
Noisy Blower
A noisy blower can be annoying and signal a problem. The noise could be due to loose parts. Tighten any loose screws or bolts. Another reason could be a dirty blower wheel. Clean the blower wheel to eliminate the noise. Worn-out bearings can also cause noise. If this is the case, replace the bearings. Ensure the blower motor is well-lubricated. This helps in reducing noise.
