Appliance repair: the best books to fix it yourself and save money
This curriculum takes a beginner from zero appliance knowledge to confident DIY diagnosis and repair across all major home appliances. It starts by building essential electrical safety and tool literacy, then moves into appliance-specific troubleshooting, and finally reaches advanced repair logic and parts-level diagnosis — each stage unlocking the vocabulary and confidence needed for the next.

- Diagnostic tools and when to use them: multimeters, thermometers, visual inspection, and listening for abnormal sounds
- Parts sourcing and compatibility: model numbers, OEM vs. aftermarket, and supplier relationships
- When to repair vs. when to call a professional or replace the appliance
- Walk through the troubleshooting process for a washing machine that won't drain: what symptoms would you observe, what components would you test, and in what order?
- Explain the safety precautions you must take before opening a refrigerator or dishwasher for repair, and why each one matters.
- Given a dryer that produces heat but doesn't tumble, what are the three most likely failure points, and how would you test each one?
- How do you use a multimeter to determine whether a heating element or thermal fuse is the problem in a range or dryer?
- Describe how to locate and interpret the model number on an appliance, and explain why it's critical for ordering the correct replacement part.
- What is the difference between a symptom and a root cause, and why does this distinction matter when diagnosing appliance problems?
- Complete a full teardown and reassembly of a non-working washing machine or dryer (with supervision if needed), documenting each step with photos and identifying all major components.
- Practice reading and sketching wiring diagrams from 'Troubleshooting and Repairing Major Appliances' for at least two different appliance types; label all components and trace current flow.
- Perform a multimeter diagnostic on a faulty heating element, thermal fuse, or motor from a discarded appliance to confirm continuity and resistance values against the book's specifications.
- Repair or replace a belt, seal, or valve on an actual appliance (washer, dryer, dishwasher, or refrigerator) following the step-by-step procedures in 'Dare to Repair'; photograph the before, during, and after states.
- Create a troubleshooting flowchart for each of the five appliance types (washer, dryer, refrigerator, dishwasher, range) based on the most common symptoms and failure modes described in both books.
- Source and order a replacement part for a broken appliance using only the model number and the part identification methods taught in the books; verify compatibility before purchase.
Next up: This stage equips you with the diagnostic mindset and hands-on skills to tackle the most frequent repairs independently; the next stage will likely deepen your expertise into less common failures, advanced electrical diagnostics, and specialized appliances (microwaves, ovens, ice makers), building on the foundation you've established here.
