Probably, it's not getting any (or enough) power.
CAUTION: That is a 220v 3-phase feed line and can give vicious burns and sometimes FATAL shocks.
Try the following:
1) Make sure that the appliance is plugged in properly.
2) Reset the Circuit Breaker that feeds the appliance a couple of times.
If that does not work and you have no experience working with High Voltage Electricity, Call For Service.
3) Check (or have checked) the Voltage in the 3-phase plug for the drier.
There are a number of possible problems when a dryer is not getting hot. If it's an electric dryer the heating element may have burned in two. Or the relay that switches power to the heating element could have gone bad. If it's a gas dryer the igniter that lites the burner could have failed. The control that commands the heat to come on could have failed. These are other possibilities

A gas dryer that will not heat usually has one of two problems. Either the gas is turned off or the heating element is burned out.
The dryer is not working properly and should be fixed. If the dryer is getting hot, but not drying the clothes you will need to clean the exhaust ductwork and exterior vent cap. It is probably clogged with lint. If the dryer is not getting hot you will need to call a repairman.
