Should a gas oven use a mechanical or digital temperature controller?

Mechanical thermostats are simple and durable, while digital models offer better readout and precision but require power, sensors and protection. Check the original control design before changing the circuit. Checklist: Define capacity, accuracy, materials and operating environment before requesting quotes on a uniform basis. Request specification sheets, test reports, certificates, maintenance manuals and spare-part lists. During acceptance, verify appearance, dimensions, functions, safety protection and packaging, and keep test records. Do not compare unit price alone; include customization, freight, spare parts, after-sales support and downtime risk. Keep written records of inquiries, confirmations, FAT, acceptance and warranty commitments.
