On certain Kmart air fryers, E4 indicates an electronic communication fault. However, its meaning can vary between models. Understanding the possible causes and knowing which checks are safe can help you decide what to do next.
What Does the E4 Error Mean on a Kmart Air Fryer?
The E4 error on certain Kmart air fryers indicates a communication problem within the electronic control system. For example, the Anko SAT15003 oven and air fryer uses E4 to indicate a signal communication fault that cannot be reset through normal controls.
Your air fryer relies on electronic components to manage cooking temperatures, timers, and other functions. These parts exchange signals to keep the appliance operating correctly. When communication fails, the air fryer may display an error and stop working.
You might see E4 immediately after switching on the appliance or while cooking. Sometimes, the display remains active, but the air fryer refuses to respond to commands. The error may also return after disconnecting and reconnecting the power.
However, E4 doesn’t mean exactly the same thing on every Kmart air fryer. Different Anko models use different electronic systems and error codes. Therefore, checking your model’s instruction manual is essential before attempting any troubleshooting.
Kmart Air Fryer E4 Error: Common Causes
Several electronic and electrical problems can affect communication within an air fryer. However, the exact cause depends on the appliance’s design and condition.
Here are five possible causes worth understanding.
1. Faulty Electronic Control Board
The electronic control board manages your air fryer’s main functions, including temperature regulation, cooking time, and operating commands. If this board develops a fault, the appliance may struggle to operate correctly.
Electronic components can fail because of heat damage, manufacturing defects, or damaged circuit connections. When the affected circuit handles communication, the air fryer may display an error instead of starting normally.
A possible sign is an E4 message appearing immediately after you switch on the appliance. The display may light up, but the controls might stop responding.
However, these symptoms don’t automatically confirm a damaged control board. Internal testing is necessary to determine whether the board or another component is responsible.
2. Poor Communication Between Internal Components
Some air fryers use separate electronic circuits for the display, buttons, and main operating functions. These components must exchange information for the appliance to work properly.
If the communication path develops a fault, signals may not reach their intended destination. Depending on the design, the problem could involve damaged connections, electronic interfaces, or other internal components.
You may notice that cooking stops unexpectedly or the control panel becomes unresponsive. In some cases, the appliance displays an error whenever you attempt to start a cooking program.
For the Anko SAT15003, E4 specifically indicates a signal communication problem. However, the manufacturer doesn’t identify which internal component causes the error.
3. Electrical Supply Problems
Your air fryer requires a suitable electrical supply to operate properly. Problems with the power cord, wall outlet, or incoming electricity can interfere with normal operation.
For instance, a loose electrical connection may cause intermittent power interruptions. Depending on the appliance’s design, these interruptions can affect electronic controls.
You might notice the display flickering, the air fryer switching off unexpectedly, or other appliances behaving unusually when connected to the same outlet.
However, electrical supply problems aren’t a confirmed cause of E4 on the Anko SAT15003. If your appliance displays this error consistently, an internal communication fault may be more relevant than the external power supply.
4. Excessive Heat Affecting Internal Electronics
Air fryers operate at high temperatures, and their internal electronic components need protection from excessive heat.
Poor ventilation, blocked air openings, or heat damage can affect electrical components over time. If the damaged part handles control signals, communication problems may develop.
One possible clue is an appliance that works briefly before displaying an error after heating up. However, this behavior can occur with several different faults.
It’s also worth understanding that the Anko SAT15003 uses separate codes for different problems. E3 indicates excessive oven temperature, while E4 indicates a communication issue.
Therefore, an E4 error shouldn’t automatically be treated as an overheating fault.
5. Moisture or Internal Electrical Damage
Moisture can interfere with electronic circuits, especially if water reaches areas that aren’t designed to get wet.
This may happen after a significant spill, improper cleaning, or exposure to damp storage conditions. Over time, moisture can also contribute to corrosion on electrical connections.
If the error appeared shortly after the appliance was exposed to water, internal moisture damage is one possibility.
However, you shouldn’t remove the casing to investigate. Internal electrical components can present safety risks, and moisture damage may remain even after the exterior appears dry.
Kmart Air Fryer E4 Error: How to Fix
The safest solution depends on your Kmart air fryer’s model and the error definition provided by its manufacturer.
For the Anko SAT15003, Kmart recommends unplugging the appliance and returning it to the store when E4 appears. The error is classified as non-resettable.
The following steps will help you identify the problem, perform safe external checks, and determine whether the appliance needs professional attention.
1. Identify Your Air Fryer Model
Start by checking the model number of your Kmart air fryer. This is important because different models may use different error codes.
You can usually find the model number on a label underneath or behind the appliance. Before checking, unplug the air fryer and allow it to cool completely.
Look for the model number and product identification details. These will help you find the correct instruction manual.
Once you’ve identified your model, check the troubleshooting section for the meaning of E4.
For example, the Anko SAT15003 identifies E4 as a communication fault that requires the appliance to be returned to Kmart.
If your manual describes E4 as a non-resettable error, avoid repeatedly restarting the appliance.
2. Switch Off and Unplug the Air Fryer
If the E4 error appears, stop using the appliance and disconnect it from the wall outlet.
Turn off the controls if they’re responsive, then remove the power plug. Avoid pulling directly on the cord because this can damage the electrical connection.
If the appliance was cooking when the error appeared, allow it to cool before touching the basket or other hot surfaces.
Unplugging prevents the appliance from operating while you identify the correct next step.
Some electronic problems may clear after a restart, but this shouldn’t be assumed for E4. The Anko SAT15003 manual specifically identifies the error as non-resettable.
Only attempt a restart if your particular model’s instructions recommend it.
If E4 remains or returns, leave the appliance unplugged and arrange the recommended service or return.
3. Inspect the Power Cord and Wall Outlet
A damaged power cord or outlet can cause electrical problems, so checking their visible condition is worthwhile.
With the air fryer unplugged, inspect the cord for cuts, exposed wires, melted insulation, or unusual discoloration.
Also examine the wall outlet without inserting anything into it. Signs of scorching, loose fittings, or a burning smell should be taken seriously.
If you notice any damage, don’t reconnect the appliance.
Next, confirm that the electrical supply matches the rating printed on your air fryer.
For example, the Anko SAT15003 is rated for 220 to 240 volts at 50 to 60 hertz. Other models may have different specifications.
A normal-looking cord or outlet doesn’t rule out an internal electronic problem. However, identifying visible electrical damage helps prevent further risks.
If you suspect an outlet fault, contact a qualified electrician.
4. Check for Blocked Ventilation Openings
Your air fryer needs adequate ventilation to release heat while cooking. Blocked air openings can cause excessive heat buildup and affect the appliance’s performance.
Begin by ensuring the air fryer is completely cool and unplugged.
Check the exterior ventilation openings for dust, grease, or objects obstructing airflow.
You can gently wipe accessible surfaces with a soft, slightly damp cloth. However, avoid pushing objects into the vents or spraying water into the appliance.
Also ensure that the air fryer has adequate clearance from walls and nearby objects.
For the Anko SAT15003, the recommended minimum clearances are:
-
20 cm above the appliance.
-
10 cm behind the appliance.
-
5 cm on each side.
These measurements apply to that particular model. Follow your own air fryer’s manual for its ventilation requirements.
Cleaning blocked vents isn’t a confirmed fix for an E4 communication fault. If your manual identifies the error as non-resettable, arrange the recommended return or service even after correcting ventilation problems.
5. Contact Kmart for a Return or Replacement
If your Kmart air fryer continues displaying E4, contacting Kmart may be the most practical solution.
For the Anko SAT15003, the manufacturer’s instructions specifically recommend unplugging the appliance and returning it to a Kmart store.

If your air fryer is still covered by its warranty, you may qualify for a repair, replacement, or refund, depending on the applicable terms and consumer protection laws.
The Anko SAT15003 includes a 12-month manufacturer’s warranty against qualifying defects. Australian consumer law may also provide rights beyond the manufacturer’s warranty period.
Avoid dismantling the appliance before contacting Kmart because unauthorized repairs can create safety concerns and may affect warranty coverage.
6. Contact a Qualified Appliance Repair Technician
If returning the appliance isn’t possible, a qualified appliance repair technician can determine whether repairing it is worthwhile.
An E4 communication fault may involve an electronic control board, damaged connections, or other internal components that require specialized testing.
A technician can assess the affected parts and determine whether suitable replacements are available.
However, some smaller air fryers have limited spare parts availability. Depending on the repair cost, replacing the appliance may be more economical.
Never attempt to bypass an error code, alter internal wiring, or repair electronic circuits without appropriate qualifications.
If the appliance produces smoke, sparks, a burning smell, or repeatedly trips a circuit breaker, stop using it immediately and seek professional assistance.
