How to check if the quartz tubes in a White Quartz Heater are working?

Oct 13, 2025

Hey there! As a supplier of White Quartz Heaters, I often get asked about how to check if the quartz tubes in these heaters are working. In this blog post, I'm gonna share some practical methods that you can use to make sure your quartz tubes are in good shape.

First off, let's understand a bit about what quartz tubes do in a White Quartz Heater. These tubes are the heart of the heater. They generate heat through infrared radiation when an electric current passes through them. This heat is then radiated into the surrounding area, warming up the space.

Visual Inspection

The easiest way to start checking the quartz tubes is by doing a visual inspection. Turn off the heater and unplug it from the power source. Safety first, folks! Once it's completely powered down, carefully remove the protective cover of the heater. You should be able to see the quartz tubes clearly.

Look for any visible signs of damage. Cracks, breaks, or discoloration are all red flags. If you see a crack in the tube, it's likely not working properly. A broken tube won't be able to generate heat efficiently, and it could even be a safety hazard. Discoloration, like a dark spot or a cloudy appearance, might indicate that the tube has overheated or there's an internal issue.

However, just because a tube looks okay on the outside doesn't mean it's working perfectly. Some internal problems might not be visible to the naked eye. That's where we need to do some more in - depth testing.

Testing with a Multimeter

A multimeter is a handy tool that can help you check if the quartz tube is conducting electricity. Set your multimeter to the resistance (ohms) setting. Make sure the heater is still unplugged from the power source.

Touch the two probes of the multimeter to the two ends of the quartz tube. If the tube is working correctly, the multimeter should show a specific resistance value. This value can vary depending on the type and specifications of the tube. You can usually find the expected resistance range in the heater's user manual.

If the multimeter shows infinite resistance (OL on most multimeters), it means there's a break in the circuit inside the tube, and it's not working. On the other hand, if the resistance is extremely low or close to zero, it could indicate a short - circuit in the tube. In either case, the tube needs to be replaced.

Functional Test

Another way to check if the quartz tubes are working is by doing a functional test. Plug the heater back in and turn it on. Set the heater to a low - heat setting at first. Stand a short distance away from the heater and feel for the heat. You should start to feel a gentle warmth within a few minutes.

If you don't feel any heat at all, it's possible that one or more of the quartz tubes are not working. You can also try using an infrared thermometer to measure the surface temperature of the tubes. Point the thermometer at the tubes and check the reading. A working tube should have a relatively high surface temperature.

Keep an eye on the heater while it's running. If you notice any strange noises, like popping or hissing sounds, it could be a sign of a problem with the tubes. Also, if the heater starts to smell funny, like a burning odor, immediately turn it off and unplug it. This could indicate that a tube is overheating or there's an electrical issue.

Importance of Regular Maintenance

Regular maintenance is key to keeping your White Quartz Heater and its quartz tubes in good working condition. Clean the heater regularly to remove dust and debris. A dirty heater can cause the tubes to overheat, which can shorten their lifespan.

Check the tubes periodically for any signs of wear and tear. If you use the heater frequently, it's a good idea to do a visual inspection and a functional test at least once a month. This way, you can catch any problems early and avoid more serious issues down the road.
