MODEL OVERVIEW
About this model: Midea MRU21C7BST
MRU21C7BST has three convertible cooling layouts and four PDF-verified pairs of flashing fault icons.
Confirm the convertible model
The Canadian Midea listing identifies MRU21C7BST as a 20-cubic-foot, 29.72-inch-wide 50/50 convertible refrigerator/freezer in stainless steel. Its upper compartment is listed as 10.9 cubic feet and its lower as 9.1. The exact product page mentions Wi-Fi, Smart+ Cooling, Multi AirFlow and four storage drawers, while explicitly marking the water filter, dispenser and AutoFill pitcher absent. The official owner PDF names MRU21C7BST and the related white MRU21C7BWW together on its cover; the table is therefore from a family manual that expressly includes the steel unit. Compare the full rating-label suffix before interpreting its icons. These faults are pairs of flashing temperature-level symbols on an internal control panel, not letter codes on a front-door display. Instructions for a different convertible Midea cabinet may use another panel.
Set up the cabinet for its chosen role
Midea calls this a freestanding refrigerator, not a recessed appliance. The installation page requests more than 100 millimetres beside and above it and 50 to 75 millimetres behind it, with a flat sturdy floor and air around the base. It calls for a grounded 115-volt outlet dedicated to the unit and tells the owner to check the actual rating plate. Levelling feet at the lower front can be adjusted so the front stands slightly higher, helping both doors close. The door-reversal section involves hinges, a signal wire and a helper, so treat that as a careful installation task rather than a remedy for a flashing sensor pattern. The product describes garage use, but gives different tested ambient ranges for fridge mode and freezer mode. Choose the intended mode and room conditions before judging whether stored food is cooling properly.
Distinguish convertible modes from alerts
The controls sit inside the upper refrigerating chamber. MODE cycles through FRZ-FRZ, REF-REF and REF-FRZ; the corresponding icon lights. TEMP selects one of four snowflake levels, from COLDEST to COLD. The first start uses refrigerator-freezer operation at 4°C in the fresh-food chamber and -20°C in the freezer according to the owner manual. In both-refrigerator mode the four presets for both chambers are 2, 4, 6 and 8°C; in both-freezer mode they are -24, -20, -18 and -16°C. A lit mode or single selected snowflake is a normal setting, not a failure. The product specification gives broader achievable ranges, so do not confuse those with the four preset values printed in the manual. Power-failure memory restores the prior state. Photograph the entire panel and mode before any reset.
Read the four paired icon faults
On rendered physical PDF page 13, Icon 7 and Icon 8 flashing together indicate a fridge temperature sensor failure. Icon 6 with Icon 8 points to the freezer defrost sensor. Icon 5 with Icon 8 identifies the ambient-temperature sensor. Icon 5 with Icon 7 identifies the freezer temperature sensor. These are positions in the manual's panel drawing, so write down the pair rather than trying to translate it into an invented E-number. Icon 8 occurs in three rows but does not mean the same fault by itself. The manual says the cabinet may still refrigerate or freeze when these warnings appear, yet directs the owner to contact a maintenance specialist. Continued cooling does not justify ignoring a persistent pattern. Record which chamber is configured as fridge or freezer, actual food temperatures and any recent mode change for the technician.
Check food and simple causes without opening controls
The troubleshooting table asks owners to check a loose plug, household power, an obstructed door, too much newly added food or a coldness setting that is too low or too high for the chosen mode. Food near the rear wall may freeze even when the compartment setting is appropriate; move it away before blaming a sensor. A recent warm load can temporarily raise the measured temperature, while a poor gasket can create condensation or frost around a vent. For routine cleaning, disconnect power, leave at least five minutes before restarting, wipe the gasket and avoid sharp defrosting tools. Do not follow an unsafe shortcut from a generic family diagram if it conflicts with the electrical or refrigerant warnings. If the icon pair returns, protect perishable food and give qualified service the exact MRU21C7BST suffix, mode, pair, temperatures and a photo.
