Common fault
Why is my oven not heating properly?
Short answer
An oven described as dead is usually still working, just to the wrong number.
Why we start there
The temperature sensor drifts as it ages, the control trusts it completely, and what you get is browning gone uneven and roasts that suddenly want another half hour, rather than an appliance that has quit. A total absence of heat is generally the cheaper fault: on gas, an igniter glowing convincingly while drawing too little current to pull the valve open, and on electric, a bake element or the relay driving it. Before any of that we need to know what fuel the range runs on, because a fair number of properties on this side of the county are plumbed for propane rather than natural gas, and that reorders the whole list.
What happens next
The propane question is not a formality. An appliance built for natural gas has to be converted to run on LP, which means the correct orifices and the regulator set for the right pressure, and a conversion done incompletely or reversed years later during a move produces symptoms that look exactly like a failing burner: lazy yellow flame, slow preheat, a broiler that will not hold, or an oven that lights fine on a mild day and struggles on a cold morning. That last one has a physical reason behind it. A propane tank that is cold and low delivers less vapor pressure, so the appliance at the end of the line is genuinely being underfed, and no part inside the range will fix it. If you are on propane, say so when you call and check the tank level before we come out.
The other half of the workload on the Wolf and Viking equipment in these kitchens is calibration and ignition, and the two get confused constantly. A drifted sensor is a measurement problem: the oven runs accurately to a wrong number, and you find it with a probe at rack level rather than by argument. A weakening glow bar igniter is a current problem: it still glows, which is why everyone assumes it is fine, but it no longer draws enough to open the valve, and the symptom is an oven that takes longer and longer to light until one day it does not. Both are ordinary parts. Neither is a reason to replace a range, and people do.
If that matches what yours is doing, say so when you call — it decides which parts come on the van.
Our Sub-Zero refrigerator lost cooling power overnight. I called early morning, and the technician arrived within hours to quickly diagnose and repair the issue. Prompt and reliable service that saved our food!
The technician expertly diagnosed a cooling problem with our older Sub-Zero unit and fixed it efficiently on-site. Polite professional service with detailed explanations. Highly recommended.
Our wine cooler had fluctuating temperatures. The technician identified and replaced a faulty sensor during a same-day visit. Efficient, knowledgeable, and reliable service in the Poway Heritage area.

Questions
Answers before you call
What actually happens on the visit, and when do I hear a number?
Airflow and the condenser first, including whether a soffit or later cabinet run closed off the heat path on a built-in retrofitted into an older Poway kitchen. Then evaporator fan draw, the coil, defrost heater continuity, thermistor resistance against the figures published for that model, gasket pull, cabinet temperature by probe. The number for parts and labor comes last, agreed before anything is fitted.
