I have this Rinnai gas dryer since 2007. It has served us well until last year August when it stopped working. When there is any loading in the dryer, it will not operate and the drum will not turn. When there is no load, the drum may turn. So, in the end, we have to let the drum turn and then load in the clothes, few pieces at a time.
After the CNY, I think it is better to get the specialist to look into this. Talking to the technical guy at Rinnai, it seems that the capacitor is faulty and needs to be replaced. The cost is about $90 (labour & Transport charges) + $25 (capacitor). He recommends to replace the motor fan belt ($58).
The appointment is scheduled for today at 10am and the technician arrives on time.
The repair work takes about 1 hour. Total bill cost is $185.11. The service is acceptable and I recommend people with problems on the gas dryer to call them (+65 6748 9011).
I have been using this gas dryer and so far, besides the capacitor issue, I think it is a good investment if you don't want to hang your clothes on poles to dry. As it uses gas to create the heat to dry the clothes, there is no weird smell and the drying process takes less then 40 minutes with full load. It saves on electricity as a typical electric dryer will take about 2 hours.
