As frustrating as it is to find your dryer not heating, figuring out why can be just as stressful. How do I fix my LG dryer that won’t heat? Decipher any displayed error codes. Next, assess for common part malfunctions like a blown thermal fuse or faulty heating element, which require replacement. Pinpoint the problem and the right solution with these common reasons for an LG dryer not heating.
Three Common Causes for an LG Dryer Not Heating
While an LG dryer not heating has specific error codes for some heating issues, other likely causes are also universal to most dryers. We’ll decipher LG heating error codes and discuss heating issues specific to gas and electric models.
Common LG Dryer Not Heating Error Codes
An error code will often appear on the display when you find your LG dryer not heating. However, if you suspect heating issues and no code is displayed, you can run a heat test to see if an error code appears.
Wondering how to test the heating element in my LG dryer? Follow these simple steps:
- Turn the dryer off
- Press and hold TEMP and SIGNAL or TEMP and DAMP DRY at the same time.
- While holding the above buttons, press the POWER until code “ln5” appears.
- Press START/PAUSE. Within 3 minutes, an error code should appear in the display.
The following LG dryer error codes indicate heating issues:
- nP or P5: Both codes correspond to power issues. nP indicates a lack of electrical current to the heater. P5 signifies improper voltage within the power cord. Make sure the dryer is properly plugged into a functioning outlet and check your home’s circuit breaker box for blown fuses or tripped breakers. If this fails to reset a LG dryer error code, a professional assessment may be necessary.
- d75, d80,d90, d95: All four codes indicate a clog in the dryer’s exhaust duct. The number corresponds to the percentage that the duct is clogged. Make sure the duct isn’t kinked or damaged before cleaning out the duct to remove the blockage.
- FlowSense Indicator: 2-4 bars on the FlowSense Indicator also indicate a blockage in the exhaust duct. Inspect the duct for damage and clean to remove blockages.
Common Heating Issues in LG Gas Dryers
In gas dryers, certain part failures are often responsible for an LG dryer not heating.
The following part malfunctions usually result in heating issues:
- Failed gas valve solenoids: these valves open the gas ports, allowing gas to flow to the burner, ignite, and heat the dryer. Watch the igniter as it tries to ignite the gas. If it glows, but the gas doesn’t light, the gas valve solenoid has likely failed. Even if just one has failed, both gas valve solenoids should be replaced.
- Faulty igniter: the igniter uses an electrical spark to light the gas as it flows to the burner. If the igniter is faulty, the gas won’t light and your LG dryer won’t heat. If the igniter doesn’t light up or shows no continuity with multimeter testing, it requires replacement.
Common Heating Issues in Electric Dryers
A burned-out LG dryer heating element is the most common heating issue for electric models. The heating element is made up of metal coils that heat up when they receive an electric current, providing heat for the dryer. If the heating element burns out and doesn’t produce heat, you’ll find the dryer running, but not heating.
If the heating element is burned out it will also show a lack of continuity with multimeter testing and require replacement.
Heating Issues Common to Both Gas and Electric Dryers
There are some heating issues that can occur in both gas and electric model dryers.
Here are some common heating problems that can affect both models:
- Incoming power issues: An electric dryer requires a 240V outlet to heat properly, while a gas dryer needs a 120V outlet to spark the igniter. Make sure the dryer is properly plugged into the right functioning outlet. Also, check for tripped circuit breakers or blown fuses in your home circuit breaker box.
- Blown thermal fuse: both model dryers have a thermal fuse that will blow if the dryer gets too hot. When this happens, the dryer won’t operate at all. While the fuse may blow if it’s faulty, it can also blow if the exhaust ducts are clogged and the dryer overheats. Check the exhaust ducts for any blockages before testing the thermal fuse for continuity. In either case, the fuse requires replacement.
