FAQS
Commercial Microwave Repair Questions
Can you repair my commercial microwave if it's still under warranty?
Yes. We can repair commercial microwaves still under manufacturer’s warranty. For the repair to be covered under warranty, contact the manufacturer directly and request a work order confirming warranty coverage and authorisation. Once we receive the valid work order, we’ll proceed with the warranty repair.
If you prefer to proceed without a manufacturer’s work order, we’re happy to repair your microwave on a chargeable basis. Either way, our repairs won’t void your manufacturer’s warranty when carried out to manufacturer repair standards.
How much does a commercial microwave repair typically cost?
Commercial microwave repair costs vary depending on the specific issue and equipment value. A simple control board replacement or door latch repair may be relatively low-cost. Magnetron replacement or power supply overhaul can be more substantial. The best way to get an accurate quote is to call us on 1300-434-380 for a free phone consultation. We’ll discuss your issue and provide ballpark costs before scheduling your appointment.
Can you fix my commercial microwave today?
We aim to complete most commercial microwave repairs same-day when parts are in stock. Call us immediately on 1300-434-380 and we’ll assess whether same-day repair is possible for your specific issue. For urgent situations where kitchen operations are affected, we prioritise immediate next-day appointments and may offer emergency service.
Should I repair or replace my commercial microwave?
This depends on repair costs versus replacement value, age of the equipment, and frequency of breakdowns. A control board or turntable replacement on newer equipment is usually worth fixing. Multiple magnetron or power supply issues on older equipment might make replacement more economical. Our technicians can assess your situation and provide an honest recommendation during inspection.
Why does my commercial microwave need a professional? Can't I fix it myself?
Commercial microwave repairs involve extremely high-voltage components (up to 5,000 volts), hazardous electrical systems, and complex magnetron technology. DIY attempts risk electrocution, severe burns, equipment damage, and voided warranties. Professional repair ensures safety, proper high-voltage testing, and lasting fixes. Our technicians are trained on all microwave types and carry genuine parts.
