Assuming you have the Cadco XAF103, there are two timers available depending on the year yours was made. The 120 minute timer above will work but very few of the XAF103's were manufactured with 120 minute timers. The majority of Cadco XAF103's were manufactured with 60 minute timers. The 60 minute timer replacement is Cadco #TM1005AO. If you need the 60 minute timer, please contact our sales team at 1.888.388.6372 to special order.
