We all know an infrared heater to be a machine and machines always get one or more issues which might seem discomforting and make us want to spend irrationally.
Worry less, things just got easier as I’m going to take us through different situational crisis an infrared space heater can develop and how to troubleshoot them taking note that the way a unit is engineered, constructed and how much it’s being used in coordination with other heat sources affects its overall efficiency.
Troubleshooting Steps For Infrared Space Heaters
Below is what you have to start looking for when your heater isn’t working.
This is not uncommon with new infrared space heaters when first used and also depends on whether the air moves past its heating elements or through the unit.
If the lamp doesn’t create much convection, there would be a lack of smell and if not, the smell should go away with time since it is basically hot dust.
Dirty heating elements can as well make the filament burn out prematurely which could be dangerous for some infrared space heaters especially when they are not new therefore careful vacuum dirt, dust from the unit while power is off.
Open the service panel and remove the heater control knob. If the unit has a separate thermostat, remove the knob and loosen the knob stem nuts and face plate mounting screws and remove the unit from the wall.
If necessary, remove the unit from the wall and open up the cabinet to access the heating element completely.
The thermostat is solely responsible for this thereby making it to shut off, produce unbearable heat or not able to heat up the environment at all.
The thermostat is an auto safety measure from the manufacturer but can be corrected by adjusting the thermostat to highest position as the case may be and you can be sure of no harm by doing this then wait for the area around infrared heater to reach the desired comfort level and then slowly turn the temperature knob back until the infrared space heater shuts off.
For one-touch electronic thermostat, the pressing the mode button it can be adjusted to the desired temperature as they are more accurate than the analog type.
You may sometimes have to check out the user’s manual for additional details when dealing with some specific product type.
Absence of a thermostat control is not recommended and could cost you more money. Avoid use of an extension cord with infrared space heaters as it could be a major fire hazard.
Warm Cord And Circuit Breaker
In most situations, a warm cord does not necessarily mean there is a problem with the heater. It might just be due to the old or worn out outlet.
If there is a loose connection between the plug and the socket that will cause resistance and also lead heat build-up. The outlet should then be replaced.
Tripping of the circuit breaker can occur when there is an overload on the outlet and other heavy appliances. All you need to do is to reset the circuit breaker.
If the fuse is blown or popped, replace with an appropriate fuse. You may also have to divert other appliances the faults to other outlets if after circuit repair it keeps tripping off.
When Infrared Space Heater Will Not Turn On?
Different factors could be responsible for this fault but for an electric infrared heater, try to ensure that the unit is plugged in and that the cord is free of damage.
If the unit has a thermostat, check that the thermostat is not set too low.
Check that the electrical socket is working properly by plugging in a known working appliance and check that the circuit breaker or fuse box is working.
For some other heaters that are powered by natural gas or propane gas.
This consequentially means that the gas tanks must be present and filled with the valve open. Ensure there are no leaks by checking for bubbles when using a spray bottle filled with soapy water to spray the pipeline.
Fix the leaks. Make sure you hear the gas coming through the heater before you try to ignite it.
If it still doesn’t work, disconnect your tubes and blow air through, if they are clogged, the air is likely to clear them out and allow them to function properly.
When Infrared Heater Will Turn On But Still Not Work
If after checking out all of the power systems and connection and they are in perfect condition, but your heater is still not working, there are other possible areas to worry about.
Start with the grill of the heater. Make sure it is free of debris, even dust as it can build up and cause problems over time. Carefully use your vacuum cleaner to clear out the front and rear grills if you think it is necessary.
Then allow your heater to run for some time, check the fans. If they are not turning or turning slowly, you may need to shut the heater down completely and clean them as well.
Also, changing the heater’s filters may help if you are not getting air flow or heat from your heater.
When Infrared Space Heater Turns On And Off?
Blocked airflow to the unit may be responsible for this. Also if there is a faulty thermostat or control switch similar thing would occur therefore remove all obstructions to heater such as furniture, drapes, plants and so on and if there are no obstruction replace the switch.
When Heater Will Not Turn Off
The unit is probably undersized for the room or the room is poorly insulated allowing heat loss which exceeds the unit’s ability to heat the space.
Insulate the walls if they are exterior and stop excessive air infiltration into the room by weather-stripping doors and windows.
An additional heater may also help to combat the issue is space is beyond the capacity of the heater you have.
When There Is Insufficient Heat Circulation
Infrared space heaters, for instance, work best when they are in direct view and much harder for the radiation to reach you when the element can’t be seen.
To combat this some infrared heater use fans to help dissipate the heat they radiate likewise other heaters too and usually make use of electricity to operate.
Check for the activity of the fan whether slow or not. If slow turn off and clean the fans as described. Those without fans or with faulty fans can make use of external fans to help circulate the heat or repair the fans.
When Only Cold Air Is Coming Out Of The Heater
Here are some common reasons why a heater may blow cool air:
- Some infrared space heaters have a fan only setting which will enable the user to use the heater as a fan. If your model has that feature, check to see if the heater is on the fan only setting.
- If the heater is on one of the heat settings, rather than the fan only setting, then it may have overheated and shut off power to the heater. Follow the reset instructions found on the heater or in the owner’s manual.
- With some digital thermostats, the fan will run for 30 seconds without heat once the set temperature is reached. This is to blow out excess heat and ensure an accurate and consistent temperature reading.
When The Electric Heater Fan Doesn’t Work?
This may be an indication of wiring not connected to the fan motor, fan blades been obstructed, bad switch, or broken fan motor.
Remove the cover, check for fan obstruction and disconnected wiring to fan.
Check for current at the motor with a volt-ohm meter. If the motor is getting current replace the motor.
When The Electric Fan Works But There Is Still No Heat?
It could be due to a defective heating element or disconnected wiring connected to the unit. Please make sure power is turned off to the electric heater at the service panel before making these repair.
Then remove the heater control knob and if the unit has a separate thermostat remove the thermostat knob.
If they are fixed to the wall loosen the knob stem nut and face plate mounting screws and remove the unit from the wall.
Check for wiring connections and tighten any loose or disconnected connections.
When There Is A Red Glow In The Heater Only Visible In The Dark
Some infrared space heaters always come with elements that glow red. If your heater has an element that should not glow red then it is possible that the light emitted from the power light causes the red glow seen.
When The Heater Is Making The Sound
Some models of heaters will make certain sounds, which are normal. For example, Radiant, Parabolic, Quartz, and Baseboard heaters will have a crackling or vibrating sound coming from them when they are first turned on.
This is caused by the heating elements expanding as they heat up which is normal.
If you feel the heat on all the heat settings then the heater is working properly as an element would both heat up and produce heat or not work at all.
