Trombetta Motor Contactors Editorial Review
This editorial review looks at customer experience and reception of Trombetta products. Customers had a lot of queries about replacements and compatibility with their appliances. The brand representatives were helpful in suggesting replacements or providing differences in the model number. Customers have generally found the product to work well for their appliances. However, some customers have reported issues with the product not working after a few months. The solenoid has been noted as an exact match for some appliances and has a faster shipping time. Some customers did note that they had to use their old bolts for install. The solenoid has been noted to work well and is cheaper than some of its alternatives. It fits well and works great for starting up lawn mowers. The polarity of some products has been noted to be different, requiring users to drill some wiring terminals in place. There were a few instances where no gaskets were sent, making the product unusable.
