Ever turned on your hob and nothing happened? Or maybe one burner sparks but won’t light, or the temperature won’t stay steady? You’re not alone. Thousands of homeowners in Brisbane and beyond face this exact problem every year. The big question isn’t just hob repair-it’s whether it’s worth fixing at all.
Yes, hobs can be repaired-most of the time
Most modern hobs, whether gas or electric, are designed with replaceable parts. That means if your burner won’t ignite, the control knob is stuck, or the surface is cracked, you don’t need to replace the whole unit. Many repairs cost less than $200 and take under an hour. A faulty ignition module on a gas hob? That’s a $60 part and a 30-minute job. A broken heating element on an electric ceramic hob? Easily swapped out.
But here’s the catch: not all repairs are worth it. If your hob is over 12 years old, or if the damage is structural-like a warped base, deep cracks in the glass, or rusted internal wiring-it’s often cheaper and safer to replace it. Older models also lack modern safety features like auto-shutoff or child locks, which make newer units more reliable long-term.
Common hob problems and how they’re fixed
Most hob issues fall into five categories. Here’s what’s likely wrong and how a technician handles it:
- Gas hob won’t light - Usually a dirty or faulty spark igniter. Technicians clean the electrode or replace the ignition module. Sometimes it’s just blocked gas ports-easily cleared with a pin.
- One burner doesn’t work - Could be a failed burner switch, broken terminal block, or damaged gas valve. For electric hobs, it’s often the heating element or thermostat. Each part is tested and replaced individually.
- Intermittent heat - This points to a failing thermostat or loose wiring. In gas models, it might be a weak thermocouple that can’t hold the gas valve open.
- Cracked glass surface - Ceramic hobs with cracks are a safety hazard. Even small cracks can let moisture in, causing short circuits. Replacement glass tops are available for most models, but the cost can hit $400-$600 depending on brand.
- Control panel unresponsive - Electronic displays and touch controls can fail due to moisture, power surges, or worn circuit boards. Sometimes a simple reset helps. If not, the control board needs replacing.
These aren’t guesswork fixes. Technicians use multimeters to test voltage, gas pressure gauges for gas hobs, and manufacturer-specific diagnostic tools. For example, Bosch and Siemens hobs have built-in error codes that flash on the display-like E01 for ignition failure or E05 for overheating. Knowing these codes cuts diagnosis time in half.
When repair isn’t the right choice
There are three clear signs you should skip repair and go straight to replacement:
- Your hob is 10+ years old - Parts become scarce after a decade. Even if you find them, they’re often knock-offs with poor warranties. A 2014 model might need a discontinued igniter that costs $120 just to source.
- Repair costs more than 50% of a new unit - If a repair quote hits $450 and a new entry-level hob is $700, you’re better off upgrading. New hobs come with better energy ratings, safety features, and a 2-year warranty.
- Multiple problems at once - If two burners are failing, the control panel is glitchy, and the glass is cracked, you’re dealing with systemic wear. Fixing one thing now means another will break in six months.
Don’t be fooled by cheap repair services that promise $99 fixes. Many use generic parts that don’t match your hob’s specs. That’s how you end up with a hob that works for a week, then blows a fuse. Always ask: "Are you using original manufacturer parts?" If they hesitate, walk away.
Gas vs electric hobs: Different repair needs
Gas and electric hobs fail in different ways-and the repair process reflects that.
| Issue | Gas Hob Repair | Electric Hob Repair |
|---|---|---|
| Common Cause | Dirty burners, faulty ignition, gas valve failure | Broken heating element, faulty thermostat, damaged circuit board |
| Typical Repair Cost | $120-$250 | $150-$350 |
| Parts Availability | Good for brands like Belling, Smeg, Ariston | Varies-ceramic hobs have fewer replacement parts after 8 years |
| Safety Risk | Gas leaks require immediate attention | Electrical faults can cause shocks or fires |
| DIY Possible? | No-gas work requires licensed technician | Some element swaps possible if you’re experienced |
Gas hob repairs are more regulated. In Australia, only licensed gas fitters can work on gas lines. Even replacing a spark module requires shutting off the main gas valve and checking for leaks with soapy water. Electric hob repairs are less regulated, but still risky if you’re not trained. A single mistake with live wires can fry your entire kitchen circuit.
How to extend your hob’s life
Prevention beats repair every time. Here’s what actually works:
- Wipe spills immediately-especially sugar and acidic sauces. They eat away at ceramic surfaces and corrode metal contacts.
- Use flat-bottomed pots. Warped pans scratch glass and create uneven heat, stressing the elements.
- Don’t slam the control knobs. The internal switches wear out from rough handling.
- Run the extractor fan while cooking. Moisture and grease buildup are the #1 killers of electronic controls.
- Every 6 months, clean the gas burner caps and ports with a toothbrush and warm soapy water. Blocked ports cause uneven flames and ignition failures.
These small habits can add 5-8 extra years to your hob’s life. I’ve seen customers who cleaned their burners yearly-some still using the same hob from 2012. That’s not luck. That’s maintenance.
What to expect when you call a technician
When you book a hob repair, here’s the process you’ll see:
- Diagnostic fee - Most charge $50-$80 to come out and check the issue. This is usually waived if you go ahead with the repair.
- Clear quote - A good technician will show you the broken part, explain why it failed, and give you a written quote before starting work.
- Parts inspection - Ask to see the old part after replacement. Reputable companies keep it for you as proof.
- Work guarantee - Look for at least a 3-month warranty on parts and labor. Some offer up to 12 months.
Avoid technicians who say "I’ll just take a look" without giving a price upfront. That’s how you get $300 bills for a $40 part. Always get the quote in writing.
When to replace instead of repair
Here’s a quick decision tree:
- Is your hob under 8 years old? → Repair is likely worth it.
- Is the repair cost under $300? → Go for it.
- Is the hob still under warranty? → Contact the manufacturer first.
- Are you planning to sell your home? → A new hob adds value and appeal.
- Do you cook daily? → Newer models save energy and reduce fire risk.
If you’re replacing, look for hobs with induction technology. They heat faster, use 20% less energy than traditional electric hobs, and are easier to clean. Brands like Siemens, Bosch, and Electrolux offer reliable models with 5-year warranties.
Can I fix my hob myself?
For minor cleaning-like unclogging gas ports or wiping down the surface-yes. But never attempt electrical or gas repairs yourself. Gas leaks can cause explosions, and faulty wiring can start fires. Even replacing a heating element requires disconnecting power and testing for residual current. Unless you’re a licensed technician, DIY repair is dangerous and often voids your warranty.
How long does a hob repair take?
Most repairs take 30 to 90 minutes. Simple fixes like replacing a spark module or cleaning burners can be done in under an hour. More complex issues-like replacing a control board or glass top-can take up to 2 hours. If the part needs ordering, you’ll need to wait 2-5 days for delivery.
Is it cheaper to repair or replace a hob?
It depends. If your hob is under 8 years old and the repair is under $300, repair wins. If it’s older, or the repair costs half the price of a new unit, replacement is smarter. A new hob costs $500-$1,500 depending on features, but you’ll save on energy bills and avoid future breakdowns.
What brands have the most reliable hobs?
Bosch, Siemens, and Electrolux consistently rank highest for reliability in Australian consumer reports. They use durable components, offer long warranties, and have wide parts availability. Cheaper brands like Westinghouse or Smeg have decent models too, but parts are harder to find after 5 years.
Do I need a gas fitter for a gas hob repair?
Yes. In Australia, only licensed gas fitters can legally work on gas appliances. This includes replacing ignition modules, valves, or hoses. Even if you think it’s just a spark issue, the gas line must be tested for leaks afterward. Using an unlicensed person is illegal and dangerous.
Final advice: Don’t wait until it fails completely
Waiting for your hob to stop working entirely is a mistake. A burner that flickers now will die completely next month. A crack that’s small today will spread under heat pressure. By then, you’re stuck cooking on one burner-or worse, without a hob at all.
Get it checked early. A $70 diagnostic call now can save you $800 in emergency replacement later. And if you’re replacing, choose a model with induction. It’s faster, safer, and lasts longer. Your future self-and your kitchen-will thank you.
