Gas stove problems often result from a faulty gas connection or ignition system, while electric oven problems often result from a bad electrical connection or fault burner. Gas stoves coupled with electric ovens rely on two separate heating systems, which can complicate repairs.
The first step for repairing a gas stove with a pilot light ignition system is making sure the pilot light hasn't gone out. Electrical ignition systems are not as easy to inspect, but many make a clicking sound and produce a visible spark. If one stove lights but others don't, the problem likely lies in the ignition system. The gas line should also be checked; inadequate or inconsistent gas flow can keep the stove from lighting.
Electric ovens often use a 240-volt connection, so making sure the unit is appropriately connected can sometimes fix problems. Ovens use one or more thermostats to check the operating temperature and determine when to start and stop producing heat. If the oven is set to broil mode and neither the top nor bottom heating element glows, the problem may be with the thermostat. If one heating element glows and the other does not, the element should be checked for signs of damage. Before replacing an element that looks intact but doesn't glow, it is worth bringing in an expert to ensure that it is connected properly.
