The same current check that catches a straining fan also catches one that is barely drawing anything. When current stays below the limit for 5 seconds, the oven beeps and shows FAN LOW CURRENT. A seized fan that has stopped, a loose connector or a failed fan motor are the usual reasons, and without that fan the control compartment heats up quickly. Middleby Marshall commercial appliance display · also shown as FAN LOW CURRENT What to do when FAN LOW CURRENT 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 Middleby Marshall Middleby Marshall ovens on this site are the kitchen's non-pizza baking and roasting work; pizza service calls belong to our pizza oven site. ### Source Middleby Marshall CTX DZ26T, DZ33T and DZ55T infrared conveyor oven owner's operating and installation manual (Rev G) CTX DZ26T, DZ33T and DZ55T infrared conveyor ovens with the touch screen (manual Rev G).

Each step comes from Middleby Marshall's own guidance for FAN LOW CURRENT on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Acknowledge the message and check whether you can hear or feel air moving at the front filter. 02 Clean the filter so that a restart gives a fair test. 03 With no air moving at all, shut the oven down and leave it that way until a technician sees it, which protects the boards. 04 Book a visit; a fan that draws too little current needs a replacement or a wiring repair behind the panels. ### 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 FAN LOW CURRENT does not describe an overloaded fan; FAN_HIGH_CURRENT covers that. It often comes before CONTROL COMPARTMENT HIGH TEMP, because a stopped fan leaves the electronics without cooling air. ## What you may notice with it.

Acknowledge the message and check whether you can hear or feel air moving at the front filter. If it comes back, it needs a visit. ### Why does my CTX oven show FAN LOW CURRENT and then a high temperature message? Once the fan stops pushing air, heat builds in the control compartment. The second message is the result of the first, so the fan is the repair. ### Can I keep baking on a CTX with FAN LOW CURRENT? It is risky. Without cooling air the boards and relays heat up fast; if the fan is silent, power down and arrange service. ### Is FAN LOW CURRENT on a CTX ever just a sensor error? It can be a loose plug or a sensing problem, but the only way to tell is to test the fan and its circuit on site. --- **[Read on the site: Middleby Marshall FAN LOW CURRENT: the CTX cooling fan is drawing too little](https://commercialappliancerepair.center/error-codes/middleby-marshall-fan-low-current/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
