Check of serviceability of functioning of system of preheat

The best way of check of a condition of components of system is their replacement on obviously serviceable. Nevertheless, there are some tests which can be made first of all.

 PERFORMANCE ORDER

  1. Attach the voltmeter or a 12-voltny lamp sampler between a wire of a food of candles of an incandescence and "weight" (metal of a body or the power unit, - grounding should reliable).
  2. Ask the assistant to include ignition and consider the measuring instrument indication, - pay attention to duration of functioning of a control lamp of preheat on a control panel and compare it to duration of giving of tension on candles.

At temperature in an impellent compartment 20°С duration of functioning of a control lamp should make 3 pages. Decrease in temperature involves increase in duration, and on the contrary.

If the lamp does not work and a food on candles does not move, the module of management or its chain электропроводки.6 can be a cause of failure

 PERFORMANCE ORDER

  1. For identification of a faulty candle, give nuts, remove washers and disconnect from candles a wire of a food and the tire, - on models of the last years of release it is rather simple to disunite contact sockets of candle electroconducting.
  2. Connect an ohmmeter between the central conclusion of a candle and "weight", - the serviceable candle has very low resistance (less than 1 Ohm). If the ohmmeter registers break (the infinite indication), therefore, the candle is faulty and is subject to replacement. It is alternatively possible to connect a lamp sampler between a wire of a food and the central conclusion of a candle, - ignition inclusion at a serviceable candle should lead to lamp activation.

In the presence of near at hand ampermeter it is possible to measure force of a current proceeding through everyone candle. After the first impulse amplitude 15 — 20 And the current should fall to 12 A.Pri an exit of result of measurement out of limits of an admissible range the corresponding candle is subject to replacement.

In summary, the candle can be turned out and checked, being guided by instructions (see. Removal, check and installation of candles of an incandescence).
