In this section, we’ll take a look at 9 of the most common problems faced by QMark users, their causes, and how you can go about solving them. Hopefully, you can get your heater running ASAP with our QMark MUH heater troubleshooting guide. Let’s dive right in. 

1. Heater Won’t Turn On

One of the most typical issues with QMark heaters is the failure to switch on. Here are the probable reasons that cause your heater not turning on.

• The circuit breaker has tripped
• The extension cord or power cord is damaged
• Problem with the electrical outlet

Solution:

You have to repair a tripped breaker. If the breaker keeps tripping, you’ll need to either unplug other appliances from the circuit or plug the heater into a different one. Check the receptacle where the heater is plugged in and reset it if necessary if the breaker hasn’t tripped.

If you’re using an extension cord, inspect it for damage. Change it for a different one. Make sure your extension cord has a higher amperage rating than the heater.

Check the power cord for damage and replace it if possible and needed. Call your electrical utility company to figure out if your power outlet matches your heater requirements. You can plug in another device and see if it runs to check if the power outlet is functioning okay.

2. Heater Suddenly Shutting Down

The most obvious reason for the problem is power mismanagement. In other cases, faulty sensors and loose wires can be notable issues. Follow either of the solutions to find a fitting cure.

Solution:

Check the Power: A standard QMark MUH Heater requires 240 volts of power. In most cases, standard power outlets in the States only come with 120 volts. Connect the heater with the right power, and it will not shut down suddenly.

Fix Loose or Broken Wires: Open up the heater and closely monitor all the wiring. Fix or replace broken wires. The connection is probably bouncing on and off for these defective wires. Once you are done fixing it, you will have a fully functioning heater. 

3. Heater Making Loud Noises

Your heater can make loud metal rubbing noises or other sorts. Also, your Qmak MUH Heater rattles after it heats up. This happens because metal expands due to heat. Nonetheless, loud ramming noises might happen either the fan is stuck somewhere or the motor is jammed. Find out the cause and follow the solution to fix it.

Solution:

Align the Fan Blades: Your fan blades are ramming against the protective grill or surroundings. This is annoying. In such cases, the possible reason for the noise is the misalignment of the fan blades.

Take out the protective grill and notice the surroundings of the blade. You might find metal scratch marks. Now, lose up the bolts that are attaching the blade to the motor. Slightly align the fan blades according to your need. Lastly, tighten the bolts to secure a good grip. Turn on the heater to find additional problems. If you don’t have any other issues, your heater will not make any noise. 

Oil the Motor: Now, if your heater motor doesn’t have proper lubrication, it will annoy you for sure. To get a remedy, you will have to lubricate the motor. In such conditions, make sure that you are not dripping excess oil inside the motor coils. Once you are done oiling, give the motor a few spins. You will have a nice and quiet heater in no time. 

4. Tripping the Breaker

Your QMark MUH heater comes with 1500W to 2500W configurations depending upon the model you buy. Every unit of QMark MUH Heater requires a proper power supply. It can be an overwhelming load for your household, especially if you don’t have the right power settings. 

Solution:

Get Proper Power: A QMark MUH Heater requires 240 Volts of power. Standard Power Units come with 120 Volts of supply. So, if you are connecting your heater with that power settings, it will likely overload your power supply. For these power failures, breakers are designed to protect the components. So, it trips down. Secure a 240 volts power outlet for your heater to avoid such issues.

5. Fan Not Working

The fans are responsible for transferring heat from the heating coils. However, due to faulty sensors, motors, or jammed blades, the fan of your QMark MUH Heater might not work. 

In such conditions, follow either of the fixes to have a fully functioning heater. 

Solution:

Jammed Motor & Blades: If your motor is jammed, you will have to clear the dirt. First, take out the blades. Then, take a blower and blow all the dirt out. Now, add lubrication to the motor. Once the clog is gone, your motor will spin again. If the fan blades are jammed somehow, you should change the blades. You might find a new blade online, but it may require a bit of hustle.

Faulty Sensors & Motors: In cases where the sensors or the motor are defective, you might want to buy a new unit. Fixing faulty sensors or replacing motors is of no good.

6. Heater Doesn’t Warm Up

If your portable heater turns on and the power light illuminates, but the heater does not provide enough heat, it could imply one of several things. The following things could be what is wrong with your heater-

1. Faulty heating elements
2. The heater isn’t set to the eco mode or set to turn on at a specific time or temperature.
3. The blower may not be working properly.

Solution:

Any of the above reasons can be behind your heater not turning hot. As it is easiest to check your thermostat settings, start with that. Make sure that the heater is in the correct mode.

Then, you need to take off your heater cover and inspect the blower fan. If it’s running fine, most probably, the heating element is the issue. A multimeter can be used to determine if one or more of the heating components are defective. Replace the heating elements if needed.

7. Bad Smell From Heater

Electric heaters should ideally be odorless, thus smelling something burning when the heater turns on isn’t a normal thing to happen. It is usually a result of dust and grease accumulation in the heating elements. 

Solution:

Dust usually burns away after a while, but if it persists, it could be due to a gunk on the heating element caused by a spill or other event in the proximity of the heater. You may generally clear this muck using a damp rag or one soaked with a solvent, such as alcohol, after gaining access to the element by removing the front grille or disassembling the heater. 

8. Heater Overheating

Heater overheating can cause your heater to shut down. Never ignore a furnace that is overheating! The problem will not go away on its own, and continuing to use your furnace could result in serious and costly damage to your system. The following things can cause a furnace to overheat.

• Restricted airflow
• Dirty internal components
• Short cycling
• Mechanical failure

You can check these issues by taking a few simple steps. 

Solution:

When there isn’t enough ventilation, the internal components of your furnace can become overly hot. This commonly occurs when you fail to replace your air filter regularly. If you live with a lot of people or have pets, you should change your filter sooner than suggested.

When the furnace switches on and off quickly or turns off prematurely during the heating cycle, this is known as short cycling. Your heater may be too big for your home. You may need to get a smaller one. 

Make sure your blower and other heater parts are functioning properly. Regular furnace tune-ups are the greatest way to ensure that your furnace’s moving parts are in good working order.

9. Heater Not Shutting Off

Here are the causes that can result in your heater not turning off-

1. Bad thermostat
2. Broken control board
3. The heater is too small for your home.

Solution:

You should test your thermostat to see if needs a repair or replacement. The problem could also be with your heater’s control board. Call in a professional if you need to get the thermostat or control board serviced or replaced.

If your heater is too small for your home, you’ll need to get another one as the primary heating source that fits your home’s size. You can use this one as a secondary one to help your central heating.
