Frymaster's gas fryers push combustion air with a blower, and an air pressure switch has to confirm that air is flowing before ignition is allowed. When the switch stays open, the FQ4000 logs E25 and holds the burner off. A blower that is dirty, blocked or not turning, or a pressure switch or its tubing that has failed, can each cause it. Frymaster commercial appliance display · also shown as HEATING FAILURE - BLOWER What to do when E25 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 Frymaster A Frymaster fryer is serviced cold: the visit waits until the oil has come down and the vat has been drained by the crew. ### Source Frymaster FilterQuick FQG30U easyTouch gas fryer manual with FQ4000 controller (error log codes, section 5.6) FQ4000 easyTouch touchscreen controller on FilterQuick fryers (FQG30U and related FilterQuick gas and electric models).

Each step comes from Frymaster's own guidance for E25 on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Turn the vat off and listen when it is switched back on: a blower that hums without spinning or makes no sound at all is worth mentioning to the technician. 02 Make sure nothing is pressed against the back of the fryer or stuffed near the blower intake, and that the fryer sits where it was installed under the hood. 03 If the message comes back, leave the vat off and book a visit to clean and test the blower and the air pressure switch. ### 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 E25 is an airflow proof problem, not a gas supply one; E28 is the burner failing to light after airflow is proven. E27 is the mirror image of E25, with the pressure switch stuck in its closed state. ## What you may notice with it. The commercial appliance problems E25 tends to arrive with.

Turn the vat off and listen when it is switched back on: a blower that hums without spinning or makes no sound at all is worth mentioning to the technician. If it comes back, it needs a visit. ### What does the blower do on a Frymaster gas fryer? It supplies the combustion air the burners need. The fryer checks that air is moving before it opens gas to the burner, which is what E25 reports on. ### Can grease on the blower cause E25 on a Frymaster? Yes. Frymaster lists a dirty or obstructed combustion air blower as a cause of slow heating and popping ignition, and heavy buildup can stop the switch from proving airflow. ### Is E25 dangerous on a Frymaster? It is a safe stop: the fryer refuses to light without proven airflow. The cost is downtime on that vat until the blower or switch is repaired. --- **[Read on the site: Frymaster E25: the combustion blower did not prove its airflow](https://commercialappliancerepair.center/error-codes/frymaster-e25/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
