Control boards, spark modules, relays — through the house wiring
St. Augustine · St. Johns County · Florida
Heavy Viking equipment, in a town that works against it
A professional range, a built-in refrigerator and a ducted hood are built to outlast the kitchen around them. Here they are asked to do it in salt air, 68 thunderstorm days a year and openings that were cut long before the appliance existed. That is what Anvil & Oak Appliance works on — one manufacturer, this county, nothing else.
Condenser fins, door hinges, stainless trim, exposed fasteners
Rear clearance, door square, the appliance’s own control pocket
Hinges, gaskets, ice-maker modules, evaporator fans, relay boards

The cheapest measurement goes first
Almost everything that comes off the van in St. Johns County traces back to one of the four cells above. What decides the bill is the order the checks run in: the measurement that can eliminate the largest part of the list is taken first, and nothing is ordered until a meter has said so. This is the order a visit actually runs in.
| Complaint | Checked first | Then | Why in that order |
|---|---|---|---|
| Fresh food warm, freezer cold | Evaporator fan and the air path | Defrost heater and bimetal | Both faults present as one warm compartment; the fan settles it in minutes |
| Oven bakes unevenly | Logged probe over three full cycles | Sensor resistance, then the burner or element | A single thermometer reading cannot see swing, and swing is usually the fault |
| Burner sparks but will not light | Electrode gap, insulator, port obstruction | Gas pressure at the manifold | The visible, no-parts fault is also the most common one |
| Upper rack still dirty | Spray-arm holes and the coarse filter | Circulation pump and feed tube | Flow is lost upstream far more often than the pump fails |
| Hood loud but weak | Duct run, roof cap, backdraft damper | Blower wheel and speed control | Delivered airflow is lost in the duct, and no new hood recovers it |
| Dead board, everything else fine | Supply and ground at the outlet | Board, then the harness to it | Surge damage arrives through the wiring, so the wiring is tested first |
Roughly 68 thunderstorm days a year in this part of Florida. Surges reach control boards through the house wiring, not through the appliance. Coastal ZIPs 32084, 32082, 32080 add salt to the condenser and the hardware. Area by area.

Notes, not marketing
- Repair or Replace a Built-In — Replacing a built-in costs more than the appliance. Here is the calculation we run on site, the questions that decide it, and the cases where we say do not repair.
- OEM Parts and the Data Plate — One appliance model can span several parts revisions. The serial number is what selects the right one, which is why we ask for it before the van is loaded.
- Measuring an Oven That Bakes Badly — Set point, average and swing are three different numbers. Most bad-baking complaints are a swing problem, and a single thermometer reading cannot see one.
- You call and describe the symptom.
- We attend, open the appliance and test it.
- A written estimate, parts and labour on separate lines.
- You approve, or you do not. The $80 stands either way.

What owners said afterwards
4.7 out of 5 from 23 customer reviews. Every one below is a single visit, in the words of the person who paid for it.Fresh food side crept up to the high forties while the freezer stayed rock solid. He pulled the lower grille, found the evaporator fan seized with salt crust off the marina air, and swapped it the same visit. No panel got marked.

Two burners on the lanai grill would light and the rest would not. He found the ignition module corroded through from ocean air, replaced it along with the electrodes, and told me to keep the cover on between cooks. All burners fire.
Dale W.2026-06-29
Both zones in the wine unit drifted to the same temperature, which defeats the point of having two. He found the divider damper stuck open and the upper sensor reading long, replaced the sensor and reset the zones.
