Kirk West Posted June 16, 2019 Report Share Posted June 16, 2019 I'm bringing a RM 2604 back to life. The AC heater unit shows open resistance so I need a new one. Can anybody tell me what wattage this heater should be? I see many available but don't know what wattage it should be. Also need the thermostat for this unit.

Lou Schneider Posted June 16, 2019 Report Share Posted June 16, 2019 The manual says the RM 2604 heating element should measure 48 ohms. That's 300 watts at 120 volts. Link to comment Share on other sites More sharing options...
Kirk West Posted June 17, 2019 Author Report Share Posted June 17, 2019 Thanks Lou. I can find one that's 295 watts so that should work. Might just take a little longer to cool. Any input on the thermostat? Measured with an ohm meter and it never opens, turn the know and it's short all the time. Thanks Link to comment Share on other sites More sharing options...

Thanks Out of curiosity, have you tried chilling the thermostat before you test it? Unlike an A/C thermostat, it's highest temperature setting is likely lower than your ambient temperature so unless there's an "off" position it may stay on at room temperatures even if it's working properly.

oldjohnt Posted June 17, 2019 Report Share Posted June 17, 2019 Kirk, After a brief search (kind of busy today) I didn't find the Heating Element or Thermostat Part Numbers, but I did find this which may or may not help, sorry best I could do in a short time. Here's a manual: http://bryantrv.com/docs2/docs/rm2604.pdf Regarding the heating element is states, same as Lou found: "This check is to be done with the heating element at room temperature. The proper ohms for RM2604 is 48 and RM2804 is 44 with a tolerance of ten percent. If the resistance is outside the tolerance range, replace the heating element." Regarding the Thermostat it states: 2.2 THERMOSTAT It is an electric only thermostat. On 2-way models it controls the AC heating element. On 3-way models it controls the DC heating element as well as the AC heating element. The thermostat regulates the cabinet temperature by making and breaking the heat source circuit. The internal mechanism breaks contact (continuity) when adequate cabinet temperature has been reached. Check the thermostat for continuity or use a jumper wire with insulated clips and bypass the thermostat. NOTE: Care should be used. Do not short to thermostat casing. Also remove the jumper after testing is completed. If the above test allows the refrigerator to operate, replace the thermostat. John T Link to comment Share on other sites More sharing options...
