Check the power cord on your Montgomery Ward refrigerator. Make sure it is plugged in correctly and that no cuts, nicks or burn marks are present. If you see either of the latter two, you either have a rodent nibbling away or there is a potential fire hazard. Address each as necessary.
Check the breaker on the main electrical panel. Make sure it is in the "On" or "Open" position and not tripped to the "Neutral" position. If the breaker is tripped, turn it to the "Off" position, then to "On." Check to see if your Montgomery Ward refrigerator has powered back on. If not, check the breaker again. Should the breaker be tripped again, there is an electrical short occurring somewhere between the appliance and electrical panel.
Check the temperature settings. On older-model refrigerators, like those sold by Montgomery Ward, these controls are sometimes accidentally turned, causing the unit to run constantly and eventually freeze up, or causing food to begin to spoil because the temperature is set too high.
Inspect the gasket seal around the Montgomery Ward refrigerator's door. If the gasket is cracked or coming lose, this causes the refrigerator to run constantly but without keeping the temperature inside well regulated.
Press the light switch in the door and wait to see if the refrigerator powers on. Because you are propping the door open and the door/light switch is engaged, the Montgomery Ward appliance ought to cycle on. If it does not, it is mostly likely the thermostat that needs to be replaced.
Listen to the condenser fan. If it rattles or shakes, it may be going bad or something may be obstructing it. Move the refrigerator out of its recess and check for obstructions. If nothing can be seen, the condenser fan may be faulty. Call a service technician to diagnose and repair the appliance.
