Heat N Glo Fireplace Turns Itself Off [7 Easy Fixes]

In this section we will examine in depth the possible reasons why your Heat And Glo fireplace keeps going out. Here you will also find the simplest solutions that we can offer you in this matter.

1.defective thermocouple

If your gas fireplace goes out after a few seconds of ignition, you may have a faulty thermocouple.

If you see the Heat And Glo pilot light come on but not ignite the burner, you can be sure that the flame sensor or thermocouple is faulty. So it doesn't detect the pilot light and releases gas from the gas valve as it should ignite the burner.

Solution:

Test the thermocouple with a multimeter. If you get a reading that isn't close to zero, your heater's thermocouple is bad. The following is the procedure for removing the thermocouple.

• First, turn the front gas valve to the off position. Give the heater enough time to cool down.
• After that, put a tarp in front of the fireplace. Remove the decorative tree trunks and place them on the tarpaulin.
• The screw holding the thermocouple in place should now be loosened. This is located on the back of the gas valve. Use a wrench.
• Finally, remove the thermocouple tip from the back of the valve and completely disconnect it from the device. To remove it you have to pull it through the bracket.

2.Upper limit switch triggered

The high limit switch is a safety device that shuts off the fireplace if it becomes dangerously overheated. This not only prevents accidents, but also protects the device from damage.

For some reason the Heat N Glo fireplace will automatically shut off when the top limit switch is triggered.

Solution:

You must reset the high limit switch and restart the heater. If the upper limit switch trips again, the following things should be checked:

• The blower must be running.
• Make sure your air filter is clean. A dirty air filter can result in low airflow causing the heater to overheat.
• Make sure the exhaust is clean. You want excess heat to exit the chimney.
• Then move any solid objects that may be blocking airflow to the heater.

Your fireplace should be working properly at this point. If the top limit switch still trips, it may be defective and need to be replaced.

3.insufficient fuel air

Sometimes the reason your fireplace isn't burning can simply be a lack of oxygen for combustion.

It could be that the room you placed the fireplace in is not adequately ventilated or something is blocking the flow of air through the heater.

Solution:

Open the living room windows and curtains to let air in. Make sure the fan is working. Otherwise it may be necessary to call in a licensed professionalReplace fan.

Also make sure the air filter is clean and the air intake is not obstructed. Clean the exhaust to release all carbon dioxide and not extinguish the flame.

4.defective heating element

Your electric heater may switch itself off due to a defective heating element. The heating element works to generate enough heat to make your home comfortable.

A defective heating element can cause the heater to overheat and activate the overheat protection switch. Therefore, your Heat N Glo fireplace will turn itself off.

Solution:

First, determine if this is the cause of your heater's frequent shutdowns. There are two techniques for testing the heating element.

1. Method:

After plugging the heater into a wall outlet, check the heating element. Check that the heating element is glowing bright orange. When the heating element glows dimly, it is no longer used.

2. Method:

Disconnect the heater from the power supply and disassemble it. Check the resistance of the heating element with a multimeter; a high resistance indicates a healthy state.

If the resistance of your heating element has decreased, you need to replace it immediately.

Replace the heating element if the results show it is defective.

5.low gas pressure

Another common reason for fireplaces to shut off automatically is lack of gas pressure.

Solution:

Pressure requirements for Heat N Glo gas fireplaces are listed below.

How to check the intake manifold pressure:

On the inlet and outlet sides of the gas regulator is an eighth (1/8) inch (3 mm) N.P.T. A male connector is provided for a test gauge connection to measure manifold pressure.

Break the center screw of the faucet with a small screwdriver. To get the pressure reading, place a rubber hose over the faucet.

During each pressure test, the fireplace and its separate isolation valve must be isolated from the gas supply piping system.

Contact your local gas supplier if the pressure test gives an incorrect gas pressure.

6.bad thermostat

A non-working Heat N Glo thermostat can cause the oven to shut down abruptly due to a poor temperature reading. This can happen if the display inside the thermostat is broken.

Sometimes the thermostat may not work due to improper placement in your home.

Let's say you've set your thermostat to a temperature that's generally higher than the rest of the house. This will cause your thermostat to misidentify the temperature.

Solution:

A multimeter can be used to determine whether the thermostat is working properly or not. If your thermostat is faulty and the multimeter shows an erratic reading, you need to replace it.

You can easily get Heat N Glo heater parts compatible with your heater.

Also, make sure the thermostat is in a location that accurately reflects the temperature of the entire room. It is not a good idea to place the thermostat near a draft or hot spot.

7.tripped circuit breaker

Many homes around the world use circuit breakers instead of fuses. It's a single gray box with multiple switches lined up neatly in rows in a typical modern home, with a single master switch at the top.

A tripped circuit breaker interrupts the power flow to the heater and turns it off.

Solution:

Check the house circuit box to see if any of the circuit breakers have tripped. Turn it back on and test the oven again if necessary.

A power outage could be the cause of the problem if it persists.

Different levels or rooms are often connected to different circuits. It's a good idea to use fewer heaters at a time or split them across multiple circuits.

frequently asked questions:

Why does my oven fan keep turning on and off?

If your oven fan cycles on and off frequently, the problem is most likely a defective fan limit switch. The heater fan limit switch is a control device that decides when to turn the fan component on and off in your oven.

How to tell if your device is short cycle?

Measuring the interval between turning your HVAC system off and on again is one way to tell if it's working properly or if it's turning on and off intermittently.

How long should an oven cycle last?

Average heater run time is 10 to 15 minutes per cycle, provided no extreme conditions are present. If your home has medium insulation, your heating system may need to run two to three times an hour to maintain the desired temperature.

What would cause an oven not to turn on?

First check the air filter for dirt. Dirty filters will result in insufficient airflow, which may result in the heater not working. Incorrect thermostat setting, closed gas shut off or defective pilot light are some of the other reasons why it won't start.

Why is it blowing cold air when the heater is on?

If a stove only produces cool air, it is possible that the heater is overheating. But no worry; this does not usually indicate that the device is defective. It is part of the heating cooling circuit.
