Appliance Repair Certification

The Appliance Repair Certification is a free intermediate-level, 20-minute skill test from Science of Apps. It tests practical household appliance repair skills — electrical safety and diagnostics, refrigeration appliances, laundry and dishwashing, and cooking appliances and customer service — written to OSHA lockout/tagout and NFPA 70E safety principles, refrigerant rules (US EPA Section 608 and the EU F-gas Regulation) and multimeter practice for 2026. Licensing and refrigerant rules vary by country, so follow local law and the manufacturer's service manual. Score 70% or more on its 20 questions to earn a verifiable Appliance Repair Proficiency certificate (SOA-ARX). Every question is based on published standards and research — including How to test continuity with a digital multimeter (Fluke), Section 608 refrigerant management (US EPA), NFPA 70E: Electrical safety in the workplace (NFPA) — and each answer is explained with its source.
