LG Gas Dryer Not Heating + Loud Tumble Noise

$100

Van Nuys CA 91405, USA

Jun 17th 2025

Our LG gas dryer (model DLGX7601WE) still powers on and spins (tumbles), but it no longer produces hot air, so it’s not drying clothes. For the past few weeks, it’s also been making a loud thumping noise while spinning — possibly an issue with the drum rollers or belt. The no-heat issue might be related to the gas ignition system (igniter, flame sensor, fuse, or thermostat), but we're not totally sure. We’re looking for someone experienced with gas dryer repairs to come inspect, diagnose, and fix it. We're happy to order and provide any parts you recommend. Located in the San Fernando Valley — flexible on timing this week! Can adjust budget depending on the repair needed etc

What do tankless water heater repair services near me include?

From daily cooking to bathing—especially during the chilly climate in America—hot water appears like a gift that keeps on giving. If you're busy preparing for winter, there’s something you might want to check, apart from ensuring your plants stay protected from snow and keeping your gutters clog-free: keeping your tankless water heater in shape. 

Come to think of it, maintaining your trusty device shouldn’t only be something you remember during winter. Not all malfunctioning heaters should immediately be replaced, too—sometimes a quick fix would do.

Getting your tankless heater water repaired immediately once warning signs appear is crucial for your health and safety. Even the most expensive or high-quality heater can experience wear and tear, so make sure to look out for the warning signs. Does it repeatedly shut down while in use? Does it fail to produce hot water? Are you disturbed by the weird noises coming from your heater? Have you noticed a discoloration in the water? 

Skip the stress and a possible spike in your energy bills by letting a Tasker handle the problem. 

Inspection and assessment

Upon your Tasker’s arrival, you can quickly discuss your concern with them just to revisit what needs to be solved. An expert would know the right equipment to prepare—a multimeter for the heating elements, ratchet and pipe wrenches, and a plumber’s tape (or Teflon tape), to name a few. Wearing their protective gear, the specialist will proceed to fixing your water heater while following safety precautions. Doing crucial repairs while inexperienced can lead to health hazards, electrical shock, or even further device damage.

Here are examples of common problems involved with tankless water heaters:

Strange noises

Is your heater suddenly producing random banging sounds? What about something similar to hissing? Any unusual sound should not be taken lightly. Strange noises are usually caused by buildup of sediments or mineral deposits, loose pipes, malfunctioning heating elements, or damages in your pressure valve, among others. Your Tasker will identify the specific kind of sound and what the culprit is. 

Inconsistent temperature

Has your heater suddenly stopped producing hot water? Or have you been experiencing fluctuations in temperature?

The ignition may be faulty, the pressure may be low, or there may be dirt accumulating in your water filter. Your Tasker can also inspect the plumbing components. A crossover may be causing the changes in temperature, which means the hot and cold water lines are getting mixed up.

There are cases where the water may be too hot, too. Usually, this points to a broken thermostat (otherwise, the setting itself is just inaccurate) or a scale buildup. Overheating can not only damage your unit, but can also endanger your well-being.

Tankless water heater leaks

Sediment buildup is a frequent culprit in many tankless water heater problems, including leaking. Other reasons may involve corrosion, issues in the internal components, and damaged connections.

Dealing with other types of water heaters? Let Airtasker help you troubleshoot, whether you’re using a commercial boiler or a gas water heater.
