LG Microwave Error Code HOT

The HOT code on an LG microwave indicates that the internal temperature in the toaster compartment has risen to an irregularly high level. This typically happens when the toaster is run without bread loaded in the slot. The unit's thermal protection system triggers this code to stop the cycle and protect internal components from heat damage.

You should not attempt to restart the toaster while the HOT code is displayed. The unit is in a protective cooling state and needs to complete the fan cycle before it can safely operate again. The microwave functions may still be available depending on the model, but the toaster function will be locked out until cooling is complete.

If the HOT code is caused by operating the toaster without bread, there is no repair cost since it is a normal protective response. If a faulty temperature sensor, thermostat, or cooling fan is found to be the cause, repair costs can range from around $75 to $200 or more depending on the specific component and labor rates in your area. A service call alone typically runs $50 to $100 before any parts are factored in.

In most cases, no repair is needed. Once the HOT code appears, simply allow the unit to complete its automatic cooling cycle, during which the fan will run for approximately 3 minutes. After the fan shuts off and the unit has cooled, you can resume using the toaster normally. Make sure bread or another food item is always loaded before starting a toasting cycle.

A manual reset is not required to clear the HOT code. The error will clear automatically once the internal temperature returns to a safe level after the cooling fan has run for approximately 3 minutes. Unplugging the unit before cooling is complete is not recommended, as it would interrupt the fan cycle needed to bring temperatures down.
