MODEL OVERVIEW
About this model: Frigidaire PRMS2790BF
The Frigidaire Professional PRMS2790BF is a 26.3-cu-ft four-door refrigerator with an external dispenser, a convertible drawer and three documented control alerts. HI is the actual displayed high-temperature label; Power Outage and Call Service are named indicators.
Identify the Professional four-door cabinet
PRMS2790BF is the Frigidaire Professional standard-depth, four-door French-door model, not one of the brand's internal-water three-door cabinets. Its exact specification gives 26.3 cubic feet: 15.8 for fresh food, 7.3 for the lower freezer and 3.2 for the convertible compartment between them. The 36-inch width and external ice-and-water dispenser are useful identity checks before using a control diagram from a shared family manual. The sheet confirms a fresh-food ice maker plus a second ice maker, while the dispenser offers cubed or crushed ice and water.
This model also has dual evaporators, a digital dispenser panel, Wi-Fi, eight refrigerator door bins and an adjustable divider in the convertible drawer. The specification marks it ENERGY STAR certified and estimates 721 kWh per year. Both air- and water-filter status indicators are fitted, but the owner's family guide lists filter part numbers for other named variants; do not assume those cartridge numbers identify PRMS2790BF. The precise suffix matters when ordering a consumable or reporting a control warning. The separate convertible compartment is central to this model's operation, so a changed drawer mode deserves attention before a temperature change is called a failure.
Read the dispenser controls before diagnosing
On the external panel, Water, Cubes and Crushed select the dispenser output. Holding Water and Crushed together for three seconds locks both the controls and access to ice and water, so an unresponsive paddle can be a deliberate lock state. The refrigerator setpoint range is 34–44°F; the freezer range is −6–6°F. The guide recommends 37°F and 0°F for a kitchen installation. These are chosen targets, not necessarily the measured air temperatures, and an unusually warm reading should be considered alongside the setpoints, open doors and any HI alert.
Chill Boost can run up to six hours and Freeze Boost up to 24, then the prior freezer setting returns. Chill Drinks is a separate freezer timer adjustable from 20 to 45 minutes; the guide warns a drink can freeze if its temperature or time is unsuitable. The display normally goes to sleep and wakes when an icon is touched. Holding Ice and Light together changes sleep behavior, whereas Cubes and Light activates Wi-Fi pairing and the display shows AP. AP is a network setup state, not a compressor fault. Record the visible panel state before changing a setting, because the same display hosts modes, alarms and connectivity cues.
Interpret HI and the two named alerts
The owner's Clear Alerts section says a high-temperature condition lights its indicator and displays HI for the compartment where it was detected. Its tone repeats every ten seconds until acknowledged; touching a key or opening a door silences the sound. HI is a real two-letter display message, but it identifies a temperature condition rather than a specific failed sensor. Note which compartment is shown, check door closure and allow the cabinet to recover while monitoring food temperature. A brief silence does not establish that cooling has returned to the desired range.
Power Outage is different: its indicator and tone occur after electrical power has been restored, and any display key silences the alarm. Check current temperatures and the condition of stored food after an interruption. Call Service is a third named indicator; the manual says it means the appliance detected an issue needing professional attention and that some functions may be unavailable even if cooling continues. Preserve that wording when contacting service. Neither Power Outage nor Call Service is an alphanumeric component code in this guide, and the manual does not turn HI into a specific repair instruction.
Use the convertible drawer without confusing modes
The Custom-Flex Temp Drawer button cycles Freezer, Meat & Fish, Drinks, Fresh Food and Wines, with a lit indicator and confirming tone. Meat & Fish selects 28°F, Drinks 32°F, Fresh Food 37°F and Wines 45°F. In Freezer mode, changing the freezer setpoint also changes the drawer; this shared adjustment is easy to overlook when comparing the drawer with the lower freezer. The model's exact sheet confirms that its convertible drawer is fitted, so these modes apply here even though the family guide also covers variants without every feature.
The guide cautions against storing fresh produce in the Custom-Flex drawer because its colder modes may freeze and damage it. It also warns not to leave glass bottles in the drawer under Freezer or Cold Drinks modes. An adjustable divider helps organize this 3.2-cu-ft space but does not alter the selected temperature. If a drink or food freezes unexpectedly, first read the lit drawer mode and freezer setpoint instead of treating that observation as HI. Conversely, a true HI message should be recorded with its compartment, even if the drawer happens to be in a temporary food setting.
Check doors, ice and service evidence
A fresh-food door that does not close may be held by packaging, cabinet alignment or the flipper mullion. The installation page explains that the mullion must meet its guide, and the troubleshooting table repeats packaging and leveling checks. Those owner checks are relevant when HI follows an open door, but they do not explain away a persistent Call Service alert. The panel also has separate air- and water-filter replacement indicators with three-second reset controls after a filter change; a lit filter reminder is not the same as the three alerts in the Clear Alerts section.
After a long power failure, ice in a bin can melt and refreeze into a clump. The guide advises emptying and drying the bin rather than forcing the dispenser or using a sharp ice pick. If dispensing is slow, its troubleshooting table lists filter seating, a clogged cartridge and the household water valve as distinct checks. Use the exact PRMS2790BF identification when obtaining the correct filter, because page 29 assigns an Er FA authentication code only to GRMC2273 and GRMG2272, not this model. For an ongoing digital error or Call Service indication, the guide directs owners to a Frigidaire service representative who can interpret the display.
