Newer R-Series cabinets use Traulsen's Smart Control. Instead of flashing text on the home screen, it keeps alarms in a menu: PFA shows the power failure alarm, and next to it the control stores how long power was off and the cabinet temperature when it came back. The cabinet temperature alarm has its own status, tCA. Traulsen commercial appliance display · also shown as Al, tCA What to do when PFA shows on the commercial appliance ### Kind of code Controls and power The controller itself is reporting trouble, or the supply behind it is: a display with dead segments, a keypad that stopped responding after steam or degreaser got behind it, relays that stick, stored recipes or cycles that vanished overnight, a blown control fuse, or one leg of a three-phase feed missing so half the heat or the pump is gone. A full power cycle at the breaker, done as the manual describes, clears a passing glitch; a code that returns, a scorched smell or any sign of moisture behind the panel means the breaker stays off, and that is a visit. ### Usually leads to Commercial controls and board repair Controllers, touch panels, relays, contactors and interlocks tested, and replaced only when the evidence says so. ### Shows up as Commercial Appliance Error Code on a Combi, Fryer, Dish Machine or Laundry Display A commercial appliance error code appears as letters or numbers on a combi, fryer, reach-in controller, dish machine or laundry machine display, or as a flashing light or an alarm tone. ### Make Traulsen A Traulsen cabinet that starts to drift gets its visit as soon as the food inside has a safe place to go. ### Source Traulsen R-Series uprights owner's manual TR35743 (04-26), 'Models After July 2025' on traulsen.com owner's manuals Described in Traulsen's R-Series uprights owner's manual TR35743 (04-26) for units built after July 2025 with the Smart Control. ## Before you book, in this order. Each step comes from Traulsen's own guidance for PFA on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Unlock the keypad, open the alarm menu and read tPd and tCu to see how long power was lost and the warmest temperature reached. 02 Decide on the food using those numbers and your health code, and log them. 03 Clear PFA from the same menu so it reads normal again. 04 If PFA keeps setting with no outage you know of, book a visit. ### Still there? It usually turns into [commercial controls and board repair](https://commercialappliancerepair.center/services/commercial-controls-and-board-repair/). Book with the code and the model number. ### What not to do PFA is a record of a power event, not a failure of the control. A cabinet temperature problem shows under tCA instead. ## What you may notice with it. The commercial appliance problems PFA tends to arrive with.

Unlock the keypad, open the alarm menu and read tPd and tCu to see how long power was lost and the warmest temperature reached. If it comes back, it needs a visit. ### How do I see how long my Traulsen lost power? In the Smart Control alarm menu, tPd shows the duration and tCu the cabinet temperature when power returned. Those two numbers are what a health inspector will ask about. ### How do I clear PFA on a newer Traulsen? The owner's manual has you go to PFA in the alarm menu and confirm twice so it reads nor. The steps start by pressing the unlock key twice. ### Why does my new Traulsen have no ELE LOS message? Units with the Smart Control keep power events in the PFA alarm menu instead of flashing text on the home screen. --- **[Read on the site: Traulsen PFA: the Smart Control recorded a power failure](https://commercialappliancerepair.center/error-codes/traulsen-pfa/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
