Fault restart method

A method for resuming operation of an icemaker after a fault is detected by a controller of said icemaker, which fault has resulted in a shutdown of said icemaker, said method comprising the steps of:

• determining if said fault relates to a first error condition or a second error condition;
• if said fault relates to said first error condition, then incrementing a fault restart tries (FRT) counter after said fault condition has been detected by said controller;
• if said fault relates to said second error condition, then bypassing incrementing of said FRT counter;
• waiting a first predetermined time period;
• after said first predetermined time period has expired, causing said controller to execute a fault restart sequence to restart said icemaker despite said detected fault condition;
• causing said controller to monitor operation of said icemaker during a cycle of operation following said fault restart sequence, and if a second fault condition is detected, again determining if said second fault condition relates to a first error condition or a second error condition, and incrementing said FRT counter only if said second fault condition relates to said first error condition, and comparing a count of said FRT counter with a predetermined maximum FRT value;
• if said count of said FRT counter equals said predetermined maximum FRT value, causing said controller to generate a fault signal and shutting down said icemaker;
• and
• if said predetermined maximum FRT value is less than said count of said FRT counter, then waiting for said first predetermined time period and causing said controller to again execute said automatic restart sequence regardless of said detected second fault condition.

A method for monitoring and resuming operation of an icemaker after a fault is detected which has caused said icemaker to shut down, said method comprising the steps of:

• detecting the occurrence of a first fault;
• determining if said first fault is a type of fault relating to an error condition other than an insufficient water supply condition;
• if said fault relates to insufficient water supply conditions, then waiting a predetermined time period before restarting said icemaker;
• if said fault does not relate to said insufficient water supply condition, then waiting said predetermined time period then incrementing a fault restart tries (FRT) timer before restarting said icemaker;
• monitoring operation of said icemaker to determine if said icemaker completes a predetermined cycle of operation without experiencing a second fault;
• if said icemaker experiences a second fault, again checking to determine if said fault relates to an insufficient water supply condition and, if not, then incrementing said FRT counter;
• determining if a count of said FRT counter equals a maximum predetermined value;
• if said count of said FRT counter does not equal said maximum predetermined value, then restarting said icemaker;
• and
• if said count of said FRT counter equals said maximum predetermined value, then generating a fault signal and aborting further attempts at restarting said icemaker.
