Combi Oven Repair in Philadelphia
Steam issues, strange error codes or a combi that refuses to cook like it used to. I provide fast, honest combi oven repair for restaurants, hotels, caterers and serious food service kitchens across Philadelphia.
Combi ovens are powerful and complex. Steam generators, drains, fans, sensors and controls all have to agree or the oven locks you out. I diagnose those systems properly instead of throwing parts at a control board.
- Factory-trained on major combi brands
- OEM-first parts sourcing
- Owner-operated service in Philadelphia
Combi Ovens Are The Workhorse Of Your Line
Combi ovens handle roasting, baking, steaming, retherm and finishing in one unit. When a combi starts to fail, it usually does not collapse in one day. It gets slower, wetter, more unpredictable and full of codes. That is where real diagnostics matter.
I work through power, gas, water, drains, fans, probes and controls so the oven cooks the way the manufacturer intended instead of limping along in a half-broken state.
Common Combi Oven Problems I Fix
Heating & Performance Issues
- Not heating properly in hot air, steam or combi modes
- Slow preheat or never reaching set temperature
- Food coming out soggy, over steamed or under cooked
- Core probe readings that do not match real product temperature
Steam, Scale & Generator Faults
- Weak steam production or over steaming
- Steam generator low water and overheat faults
- Scale buildup in boilers, tanks and piping
- Level probes, fill valves and sensors fouled with scale
Fans, Doors & Drains
- Fans not running, running noisy or cycling off on faults
- Doors leaking steam, blown gaskets and faulty door switches
- Standing water in the cavity or slow draining
- Drain valve codes and drain over temperature warnings
On every job the goal is simple: find the real failure, explain it plainly and repair it in a way that survives a busy service.

Strange Error Codes And Fault Messages
Modern combi ovens throw a lot of codes: E01, E03, E11, Service 26, drain valve faults, probe errors and steam generator overheat warnings show up constantly on units from Rational, Alto-Shaam, Convotherm and similar brands.
Most of the time the code is pointing at a category of problems, not one guaranteed part. For example:
- Low water or steam generator overheat codes caused by scale, blocked level probes or weak fill valves
- High cavity temperature or sensor errors tied to failing probes, wiring damage or stuck contactors
- Fan and motor errors traced to blocked wheels, bad bearings, motor protection trips or VFD issues
- Door and drain faults that come from limit switches, poor sealing, misalignment or sticky drain valves
I use the code as a starting point, then test the steam, air, water and electrical systems so we are changing the right part the first time.
How A Combi Oven Service Call Works
- Quick intake. You tell me what the oven is doing, which modes are failing, what codes you see and how long it has been going on.
- On site diagnostics. I check power, gas, water, drain operation, steam generation, fans, sensors and safety circuits with real tests, not just a visual once over.
- Repair on the spot when possible. If the issue is something I can resolve safely with parts on hand or practical adjustments, I fix it in one visit.
- Clear estimate for parts. When OEM parts need to be ordered, you get a simple breakdown and realistic timeline before anything is purchased.
No mystery charges and no surprise add ons. Just a clear diagnosis and a fair path to getting your combi back in service.
Who I Work With
I focus on commercial and institutional kitchens that lean heavily on their combi ovens every day:
- Independent restaurants and neighborhood spots
- Hotel and banquet kitchens
- Catering and commissary operations
- School, campus and healthcare kitchens
- High volume cafes and concept kitchens using combis for bread, roasts and retherm work
If a combi oven being down puts your menu in trouble, I treat that like a priority.

Combi Oven Repair FAQ
Can you repair both gas and electric combi ovens?
Yes. I work on gas and electric combi ovens with boiler and boilerless designs across most major brands, including Rational, Alto-Shaam, Convotherm, Blodgett, Henny Penny, UNOX and Cleveland.
Can you help with scale and water treatment for my combi?
I can inspect your steam generator, piping and existing filtration, then recommend descaling, service and filtration upgrades so you are not constantly replacing expensive components due to scale.
What if my combi keeps rebooting or locking out during service?
Reboots and lockouts usually point to power, board, safety or sensor issues. I follow the fault patterns, test the electrical side and verify what is actually failing instead of clearing codes and hoping they do not come back.
Is my combi worth repairing or should I replace it?
On older units or heavily scaled ovens, I will walk you through repair cost versus realistic remaining life so you can decide whether to repair, rebuild or start planning a replacement.
