Common Issues
Dealing with a Mr Heater Big Maxx that isn’t working can be frustrating. Understanding common issues can help you troubleshoot effectively. Let’s look at some frequent problems and how to address them.
No Heat
One of the most common issues is when the heater doesn’t produce heat. Check the power supply first. Ensure it’s connected properly. Verify that the circuit breaker hasn’t tripped. Next, inspect the thermostat. Make sure it’s set to the desired temperature. If it’s faulty, replace it. Clean the heater’s air intake and exhaust vents. Blocked vents can prevent proper heating. If all else fails, the problem might be with the gas valve or control board. You may need a professional to fix these parts.
Strange Noises
Strange noises from your heater can indicate several issues. A clicking sound often means there’s a problem with the ignition system. Check for any loose connections or faulty components. A rattling noise can be due to loose screws or parts inside the heater. Tighten any loose parts you find. If you hear a whistling sound, it could be due to a gas leak. Turn off the heater immediately and check the gas connections. If the noise persists, consult a professional for a thorough inspection.

Basic Checks
When troubleshooting your Mr Heater Big Maxx, start with the basic checks. These initial steps can often resolve common issues quickly and efficiently. Ensuring your heater is functioning properly is crucial, especially during colder months.
Power Supply
First, check the power supply. Ensure the heater is plugged in securely. Sometimes, the plug might be loose, causing the heater to malfunction. Verify that the power outlet is working by testing it with another device.
If the outlet is functional and the heater is plugged in, inspect the power cord for any visible damage. Look for frays, cuts, or exposed wires. A damaged power cord can prevent the heater from receiving power and pose a safety hazard.
Next, check the circuit breaker. The breaker might have tripped, cutting off power to the heater. Locate your home’s breaker panel and see if the switch for the heater’s circuit is in the “off” position. If it is, switch it back to “on”.
Gas Connection
After checking the power supply, move to the gas connection. Ensure the gas valve is open and supplying gas to the heater. A closed valve will prevent the heater from igniting.
Inspect the gas line for any leaks. Use a solution of soap and water to check for bubbles around the connections. If you see bubbles, there is a leak, and the gas line needs to be tightened or replaced.
Additionally, ensure the gas pressure is adequate. Low gas pressure can cause the heater to malfunction. You may need to consult your gas provider or a professional technician to verify the gas pressure.
Lastly, check the pilot light. If the pilot light is not lit, the heater will not function. Follow the manufacturer’s instructions to relight the pilot light safely.

Thermostat Problems
One common issue with the Mr Heater Big Maxx is thermostat problems. The thermostat controls the temperature, so if it malfunctions, the heater may not work properly. Let’s dive into some common thermostat issues and how to address them.
Calibration
Sometimes, the thermostat may be out of calibration. This means it does not read the temperature correctly. You may notice the heater turns on and off at the wrong times.
To check the calibration:
- Compare the room temperature with a reliable thermometer.
- Check if the thermostat reading matches the thermometer.
- If not, adjust the thermostat following the manufacturer’s instructions.
Replacement
If calibration does not solve the problem, the thermostat may need replacement. Here is a simple guide to replace the thermostat:
- Turn off the power to the heater.

Ignition Failure
Encountering ignition failure with your Mr Heater Big Maxx can be frustrating. This issue is common and can often be resolved with some simple troubleshooting steps. Below, we will explore the two main components involved in ignition: the pilot light and the igniter.
Pilot Light
The pilot light is crucial for your heater’s operation. If it goes out, the heater won’t ignite.
- Check if the pilot light is lit. If not, try relighting it.
- Ensure the gas supply valve is open. No gas, no flame.
- Inspect the pilot light opening for any blockages. Clean if necessary.
If the pilot light still doesn’t stay lit, it might be a thermocouple issue. The thermocouple senses the pilot flame and signals the gas valve to stay open. If faulty, it prevents the gas from flowing.
| Problem | Solution |
|---|---|
| Pilot light won’t stay lit | Check and clean the thermocouple |
| Pilot light is weak | Adjust the pilot light flame |
Igniter
The igniter creates the spark needed to ignite the pilot light. If it’s not working, the heater won’t start.
- Listen for a clicking sound when you press the ignition button. No sound indicates a problem.
- Check the igniter for any visible damage or dirt. Clean or replace it if necessary.
- Ensure the igniter electrode is close enough to the pilot light. A gap can prevent ignition.
If your igniter still fails, it may require a replacement. Use a multimeter to test the igniter’s continuity. If it shows no continuity, replace the igniter.
By following these steps, you can often resolve ignition issues with your Mr Heater Big Maxx. Regular maintenance and prompt troubleshooting keep your heater running smoothly.
