DeLonghi PAC 400 Transformer
A basic electrical transformer is used for many products which also includes your heating system as it converts a certain amount of electricity to a different voltage, 120V to 12V, for example. Heating and cooling transformers are all different and you should be aware of the specific necessary voltage readings. If a replacement is necessary, then it would be a good idea to buy one that is assessed for the correct voltage for the sake of safety.
Major symptoms the electrical transformer has to be replaced
- Extremely low voltage exiting a main transformer using a voltmeter
- Wrong voltage is found coming from the system transformer
- System transformer physically appears melted or have a burning smell while electricity is running through it
