MHEC1737D
LG MHEC1737D Air Fry Microwave Repair
Most common issues on this model
- Convection fan and heater that do not brown or crisp
- Air fry mode that stops early
- ThinQ app connection
- Vent fan speeds and filters
- Door latch, switches and mounting bracket
The MHEC1737D is an over-the-range convection microwave with a 1.7 cu. ft. capacity, air fry, Sensor Cook and ThinQ app features. A second model number, the MHEC1737F, shares its page. It hangs above the cooktop and does a convection oven’s job in a microwave’s footprint.
Convection and air fry add a heater and a fan that a plain microwave does not have, so we test them as their own system. We run convection and air fry, listen to the fan, check for heat and watch for overheating shutdowns. For the smart side we check the app connection. The vent fan, filters, latch and bracket get the standard over-the-range review.
Both model numbers share a platform, so we read the label before ordering parts. We quote in writing first, and our repair has a 30-day warranty.

What do you check when air fry does not crisp food?
We test the convection heater, the fan that moves the hot air and the temperature sensing. Air fry relies on all three, so a weak one gives pale food and long cook times.
Is the MHEC1737F the same microwave?
LG lists the MHEC1737F as a variant on the same page. We confirm which one you have from the label before we order any part.
My ThinQ app will not find the microwave. What now?
We check the microwave's power and control first, then the home network settings and the pairing steps with you, so the app can reach it again.
