MHEU1738N
LG SIGNATURE MHEU1738N Microwave Repair
Most common issues on this model
- Convection heater and fan during Air Fry
- Air Sous Vide mode that will not hold its program
- Sensor Cooking results
- Vent fan speeds and filters
- Door latch, switches and mounting bracket
The MHEU1738N is a 1.7 cu. ft. over-the-range microwave from the LG SIGNATURE Tailored Collection. LG lists Air Fry, Convection Technology, Air Sous Vide and Sensor Cooking. It is also offered as the MHEU1738X, and it sits over a range in a high-end kitchen.
The multi-mode design gives us several systems to confirm. We run Air Fry and convection, listening to the fan and watching for heat. We try Air Sous Vide and Sensor Cooking to see that each mode starts and holds its program. The vent hood side gets its own test, with fan speeds, filters and the duct path, followed by the latch, switches and bracket.
We read the model and serial label first, since the two model numbers share a page. A written price comes before work, and the repair has a 30-day warranty.

What is Air Sous Vide on the MHEU1738N?
LG lists it as one of this microwave's cooking modes. If it will not start or hold a program, we test the control and the heating and fan parts that mode relies on.
Is the MHEU1738X the same oven?
It is listed as a second model number for the same microwave. We read your label to confirm which one is installed before ordering a part.
Why does Air Fry run but not brown food?
Browning needs the convection heater and fan to work together. We test both and the temperature sensing, and we check for overheating shutdowns that cut the heat short.
