Disconnect it from the board and measure the resistance across its two leads with a meter. At 120V, the resistance is about 14,400 divided by the watts (for example, about 72 ohms for a 200W heater). An open (infinite) reading means it's burned out. Also check from each lead to the metal housing. It should read open. Note that the 61745322 is based on the cooling unit's serial number (below 11200050), and it's discontinued.
