Many Turbo Air models have a patented self-cleaning condenser: a small motor runs a brush up and down the coil on a schedule, once every three days by default. S1 and S2 say the brush did not close its end switch in time, so it may be jammed, the motor may be weak or a switch may be out of place. Turbo Air commercial appliance display · also shown as S2 What to do when S1 shows on the commercial appliance ### Kind of code Motors and drives Something that should turn is not turning, or not at the speed the controller expects. A washer-extractor's drive or its inverter may stop the spin when the load is out of balance or a bearing drags, a tumbler's belt may slip so the drum barely moves, a convection or combi fan may slow on worn bearings and bake unevenly, and a dish machine's wash pump may hum without spraying. Redistributing a load, confirming the door is latched and running the machine's own test cycle are fair; a drum, a belt or a motor is a visit, and nobody reaches into a drum that could still move. ### Usually leads to Commercial laundry machine repair Coin, card and on-premise laundry machines and tumblers: door locks, bearings, inverters, burners and payment hardware. ### 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 Turbo Air Turbo Air cabinets in a busy kitchen tend to get a visit between shifts, with the manager present to sign off the log. ### Source Turbo Air PCB settings service sheet (control menu and error codes), turboairinc.com resource center Read from the error code item (ER) of the control menu, opened by holding both temperature buttons until SL shows, as laid out on Turbo Air's PCB settings sheet. ## Before you book, in this order. Each step comes from Turbo Air's own guidance for S1 on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Unplug the unit before touching the condenser area. 02 Look for a towel, carton or debris caught in the brush track. 03 Clean off heavy grease; Turbo Air notes the brush may not remove grease. 04 If S1 or S2 returns, book a visit for the cleaner motor and switches. ### Still there? It usually turns into [commercial laundry machine repair](https://commercialappliancerepair.center/services/commercial-laundry-machine-repair/). Book with the code and the model number. ### What not to do S1 and S2 are not cooling failures, but a stalled brush means the condenser is no longer being cleaned. A condenser that fills with dust will soon lead to C1. ## What you may notice with it. The commercial appliance problems S1 tends to arrive with.

Unplug the unit before touching the condenser area. If it comes back, it needs a visit. ### What is the self-cleaning condenser on a Turbo Air? A motorized brush that sweeps the condenser coil on a schedule. The sheet sets it to run once every three days by default. ### Why does my Turbo Air show S1? The condenser brush did not reach its switch in time. Look for something jamming the brush with the unit unplugged. ### Do I still need to clean a Turbo Air self-cleaning condenser? Turbo Air still recommends blowing the coil out with nitrogen once or twice a year, and the brush may not remove grease. --- **[Read on the site: Turbo Air S1 and S2: the self-cleaning condenser brush did not finish its stroke](https://commercialappliancerepair.center/error-codes/turbo-air-s1/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
