WE have been using a home appliance extended warranty company and had some repairs and replacements. They are starting to play games about providing repair service on our current built in microwave. Extended warranty companies are not in business to provide help, they want to make money. If you can get one before signing up, read the policy over very carefully looking for loopholes and proof of OEM scheduled paper work required when making claims. Generally it's better to keep money aside for repairs and replacements after original warranty periods on chassis and housebox content run out.
