HEAT RELAYS FOR CLASSIC ELECTRIC COMBOS AND DRYERS
As Tom said mentioned my brother Jeff and I have been installing heater relays on classic machines for at least 25 years. We normally try to bypass the timer, the temperature or program switch and the motor centrifugal switch these are all parts that are difficult if not impossible to replace on classic machines. You should not ever bypass the heater safety thermostat in case the relay contacts ever stick, that way you have a safety backup. I usually get a relay with a 208-240 volt coil and an contact amp rating of at least 30 amps at 240 volts.remember thier is no 220 power in this country most homes have 230-250 volt power if you have single phase power, many commercial buildings and apartments and condos have three phase power in which case you end up with just 208 volts which ends up producing 25% less heat than 240 volts.
